Bistatic RCS generated by dielectric spheres

Note that the following notebook is very compute intensive. To speed it up disable the near-field computations.

In this notebook, we consider the bistatic radar cross section generated from plane wave scattering by an array of dielectric spheres $\Omega_j$, each with its individual permittivity $\epsilon_j$ and permeability $\mu_j$.

We denote by $\epsilon_{0}$ and $\mu_0$ the electric permittivity and magnetic permeability in vacuum, and by $\epsilon_{r, j} = \frac{\epsilon_j}{\epsilon_0}$ and $\mu_{r, j} = \frac{\mu_j}{\mu_0}$ the relative permittivity and relative permeability for each dielectric object. Denote by $\mathbf{E}^\text{s}$, $\mathbf{H}^\text{s}$ the scattered electric and magnetic field in the exterior of the scatterers. Moreover, let $\mathbf{E}$ and $\mathbf{H}$ be the total exterior fields. Correspondingly, we denote the interior fields in the $j$th obstacle by $\mathbf{E}_j$ and $\mathbf{H}_j$.

For a given medium, we normalize the Maxwell equations by setting $\hat{\mathbf{H}} = \sqrt{\mu}\mathbf{H}$ and $\hat{\mathbf{E}} = \sqrt{\epsilon}\mathbf{E}$ and obtain

\begin{align} \nabla\times \hat{\mathbf{E}} &= \mathrm{i}k \hat{\mathbf{H}},\nonumber\\ \nabla\times \mathbf{H} &= -\mathrm{i}k \mathbf{E}.\nonumber \end{align} with $k=\omega\sqrt{\mu\epsilon}$.

The electric field equations for the dielectric scattering problem now take the form \begin{align} \nabla\times\nabla\times \hat{\mathbf{E}}^{s}(x) - k_0^2\hat{\mathbf{E}}^{s}(x) &= 0,~x\in\Omega^{+}\nonumber\\ \nabla\times\nabla \times \hat{\mathbf{E}}_{j}(x) - k_j^2\hat{\mathbf{E}}_{j}(x) &= 0,~x\in\Omega_j\nonumber\\ \end{align} with $k_0 = \omega\sqrt{\epsilon_0\mu_0}$ and $k_j = k_0\sqrt{\epsilon_{r,j}\mu_{r,j}}$.

We still have to fix the correct boundary conditions between the media.

We denote the interior tangential trace of the electric field $\mathbf{E}_{j}$ at the $j$th obstacle as $\gamma_\text{t}^{j, -} \mathbf{E}_{j} = \mathbf{E}_{j}\times \nu$ with $\nu$ the exterior normal direction on the boundary of $\Omega_j$. Correspondingly, we define the exterior tangential trace $\gamma_\text{t}^{j, +}\mathbf{E} = \mathbf{E}\times \nu$. Moreover, we define the interior Neumann trace as $\gamma_\text{N}^{j,-} \mathbf{E}_{j} = \frac{1}{\mathrm{i}k_j}\gamma_\text{t}^{j,-}\left(\nabla\times \mathbf{E}_{j}\right)$ and the exterior Neumann trace as $\gamma_\text{N}^{j,+} \mathbf{E} = \frac{1}{\mathrm{i}k_0}\gamma_\text{t}^{j,+}\left(\nabla\times \mathbf{E}\right)$.

The boundary conditions on the $j$th obstacles are that the tangential component of the electric and magnetic field is continuous across the boundary. Taking the rescaling into account this implies the conditions \begin{align} \gamma_\text{t}^{j, -}\hat{\mathbf{E}}_j &= \sqrt{\epsilon_{r,j}}\gamma_\text{t}^{j,+}\hat{\mathbf{E}}\nonumber\\ \gamma_\text{N}^{j, -}\hat{\mathbf{E}}_j &= \sqrt{\mu_{r,j}}\gamma_\text{N}^{j,+}\hat{\mathbf{E}}. \end{align} Towards infinity we need to satisfy the Silver-Müller radiation conditions, which are given as $$ \lim_{|\mathbf{x}|\rightarrow\infty}|\mathbf{x}|\left(\hat{\mathbf{H}}^\text{s}(\mathbf{x})\times \frac{x}{|x|} - \hat{\mathbf{E}}^\text{s}(\mathbf{x})\right) = 0 $$ uniformly in all directions.

In the following we describe a formulation based on the multitrace operator $\mathsf{A}:=\begin{bmatrix}\mathsf{H} & \mathsf{E}\\ - \mathsf{E} & \mathsf{H}\end{bmatrix}$ whose implementation in Bempp is described in more detail in Scroggs, Betcke, Smigaj (2017). Here, the operator $\mathsf{H}$ is the magnetic boundary operator and $\mathsf{E}$ is the electric boundary operator. The operator $\mathsf{A}_{j,+}$ associated with the exterior solution on the boundary of $\Omega_j$ satisfies $$ \left[\frac{1}{2}\mathsf{Id} - \mathsf{A}_{j,+}\right]\begin{bmatrix}\gamma_\text{t}^{j,+}{\hat{\mathbf{E}}^\text{s}}\\ \gamma_\text{N}^{j,+}{\hat{\mathbf{E}}^\text{s}}\end{bmatrix} = \begin{bmatrix}\gamma_\text{t}^{j,+}{\hat{\mathbf{E}}^\text{s}}\\ \gamma_\text{N}^{j,+}{\hat{\mathbf{E}}^\text{s}}\end{bmatrix}, $$ where $\mathsf{A}_{j,+}$ is the multitrace operator on the boundary of $\Omega_j$ with wavenumber $k_0$. The interior solutions $\mathbf{E}^{j}$ satisfy $$ \left[\frac{1}{2}\mathsf{Id} + \mathsf{A}_{j,-}\right]\begin{bmatrix}\gamma_\text{t}^{j,-}{\hat{\mathbf{E}}_j}\\ \gamma_\text{N}^{j,-}{\hat{\mathbf{E}}_j}\end{bmatrix} = \begin{bmatrix}\gamma_\text{t}^{j,-}{\hat{\mathbf{E}}_j}\\ \gamma_\text{N}^{j,-}\hat{\mathbf{E}}_j\end{bmatrix}, $$ where $\mathsf{A}_{j,-}$ is the multitrace operator across the boundary of $\Omega_j$ with wavenumber $k_j$.

Now denote by $\hat{V}_j^\text{s}:=\begin{bmatrix}\gamma_\text{t}^{j,+}\hat{\mathbf{E}}^{s}\\ \gamma_\text{N}^{j,+}\hat{\mathbf{E}}^\text{s}\end{bmatrix}$ the vector of trace data associated with the scattered field on the boundary of $\Omega_j$. Correspondingly, we denote by $\hat{V}_j$ the vector of the trace data of the interior solution in $\Omega_j$ and by $\hat{V}^\text{inc}$ the vector of trace data of the incident field on the boundary of $\Omega_j$.

We first consider the case of a single scatterer $\Omega_1$. The boundary conditions are given by $$ \hat{V}_1 = \begin{bmatrix}\sqrt{\epsilon_{r, 1}} & \\ & \sqrt{\mu_{r, 1}}\end{bmatrix}\left(\hat{V}_1^\text{s} + \hat{V}_1^\text{inc}\right)=: D_1\left(\hat{V}_1^\text{s} + \hat{V}_1^\text{inc}\right). $$ From $\left(\frac{1}{2}\mathsf{Id} + \mathsf{A}_{1,-}\right)\hat{V}_1 = \hat{V}_1$ together with the above relationship for the exterior multitrace operator, and the boundary condition, we obtain that $$ \left(\frac{1}{2}\mathsf{Id} + \mathsf{A}_{1,-}\right)D_1\left(\hat{V}_1^\text{s} + \hat{V}_1^\text{inc}\right) = D_1\left(\frac{1}{2}\mathsf{Id} - \mathsf{A}_{1,+}\right)\hat{V}_1^\text{s} + D_1\hat{V}_1^\text{inc}. $$ Simplifying the above equation leads to $$ \left(D_1^{-1}\mathsf{A}_{1,-}\mathsf{D}_1 + \mathsf{A}_{1, +}\right)\hat{V}_1^\text{s} = \left(\frac{1}{2}\mathsf{Id} - D_1^{-1}\mathsf{A}_{1, -}D_1\right)\hat{V}^\text{inc}. $$ Now assume that we have a whole array of scatterers. Then the incident wave of the $j$th scatterer is the sum of the global incident wave plus the scattered waves from all other scatterers. This results in the equation $$ \left(D_j^{-1}\mathsf{A}_{j,-}D_j + \mathsf{A}_{j, +}\right)\hat{V}_j^\text{s} = \left(\frac{1}{2}\mathsf{Id} - D_j^{-1}\mathsf{A}_{j, -}D_j\right)\hat{V}^\text{inc} - \sum_{i\neq j}\left(\frac{1}{2}\mathsf{Id} - D_j^{-1}\mathsf{A}_{j, -}D_j\right)\mathsf{A}_{i,j}\hat{V}_i^\text{s} $$ for each scatterer $j$. The operator $-\mathsf{A}_{i, j}$ maps scattered trace data on the $j$th scatterer to exterior trace data on the $i$th scatterer. It is just the exterior Stratton-Chu formula, hence the minus sign. To implement $\mathsf{A}_{i, j}$ one just implements the multitrace operator with domain space on one obstacle and test space on the other obstacle.

If there are $N$ obstacles then the above formula leads to a block operator system with $2N$ equations in $2N$ unknowns, whch is fully determined. In the following we demonstrate the implementation of this system in Bempp.

We start with the usual imports and enable console logging.

import bempp.api
import numpy as np

bempp.api.enable_console_logging()
bempp.api.global_parameters.hmat.eps = 1E-5

For this notebook we will use three spheres of radius 0.4, centered at $-1$, $0$, and $1$ on the x-axis.

centers = [-1, 0, 1]
radius = .4

number_of_scatterers = len(centers)

grids = [bempp.api.shapes.sphere(r=radius, origin=(c, 0, 0), h=0.1)
        for c in centers]

02:15:33:Host 5880b86bc3ef:Rank 0:root:INFO: Created grid with 636 elements, 320 nodes and 954 edges.
02:15:33:Host 5880b86bc3ef:Rank 0:root:INFO: Created grid with 652 elements, 328 nodes and 978 edges.
02:15:33:Host 5880b86bc3ef:Rank 0:root:INFO: Created grid with 636 elements, 320 nodes and 954 edges.

We now define the associated constants and material parameters. We have chosen the material parameters for Teflon. The overall simulation will be running at a frequency of 300Mhz.

frequency = 300E6 # 300Mhz

vacuum_permittivity = 8.854187817E-12
vacuum_permeability = 4 * np.pi * 1E-7

rel_permittivities = number_of_scatterers * [2.1]
rel_permeabilities = number_of_scatterers * [1.0]

k0 = 2 * np.pi * frequency * np.sqrt(vacuum_permittivity * vacuum_permeability)
wavenumbers = [k0 * np.sqrt(er * mr) for er, mr in zip(rel_permittivities, rel_permeabilities)]
print("The exterior wavenumber is: {0}".format(k0))
print("The interior wavenumbers are:")
print(wavenumbers)

The exterior wavenumber is: 6.287535065634769
The interior wavenumbers are:
[9.111503944099038, 9.111503944099038, 9.111503944099038]

We now assemble the incident wave field. To that affect we choose a z-polarized plane wave travelling at an inciden angle theta in the (x,y) plane. Note that we already scale it with $\sqrt{\epsilon_0}$ to obtain the field $\hat{\mathbf{E}}^\text{inc}$.

theta = np.pi / 4 # Incident wave travelling at a 45 degree angle
direction = np.array([np.cos(theta), np.sin(theta), 0])
polarization = np.array([0, 0, 1.0])

def plane_wave(point):
    return polarization * np.exp(1j * k0 * np.dot(point, direction))

def scaled_plane_wave(point):
    return np.sqrt(vacuum_permittivity) * plane_wave(point)

def tangential_trace(point, n, domain_index, result):
    result[:] =  np.cross(scaled_plane_wave(point), n)

def scaled_plane_wave_curl(point):
    return np.cross(direction, polarization) * 1j * k0 * np.sqrt(vacuum_permittivity) * np.exp(1j * k0 * np.dot(point, direction))

def neumann_trace(point, n, domain_index, result):
    result[:] =  1./ (1j * k0) * np.cross(scaled_plane_wave_curl(point), n)

Before we setup the left-hand side block operator matrix we write a small routine that rescales a given $2\times 2$ block operator matrix $A$ to $D^{-1}AD$, where $D$ is a diagonal matrix defined by its diagonal elements $d_1$ and $d_2$.

def rescale(A, d1, d2):
    """Rescale the 2x2 block operator matrix A"""
    
    A[0, 1] = A[0, 1] * (d2 / d1)
    A[1, 0] = A[1, 0] * (d1 / d2)
    
    return A

We now create all the scaled interior multitrace operators and the non-scaled exterior multitrace operators.

scaled_interior_operators = [
    rescale(bempp.api.operators.boundary.maxwell.multitrace_operator(
        grid, wavenumber), np.sqrt(epsr), np.sqrt(mur)) for grid, wavenumber, epsr, mur in
            zip(grids, wavenumbers, rel_permittivities, rel_permeabilities)
]

identity_operators = [
    bempp.api.operators.boundary.sparse.multitrace_identity(grid, spaces='maxwell')
    for grid in grids
]

exterior_operators = [
    bempp.api.operators.boundary.maxwell.multitrace_operator(
        grid, k0) for grid in grids
]

We can now loop through the rows of the left-hand side block system to create all block operator entries. We will store the filter operators $\frac{1}{2}\mathsf{Id} - D_j^{-1}\mathsf{A}_{j, -}D_j$ and the transfer operators $\mathsf{A}_{i,j}$. The filter operators will be needed for the right-hand side, and the transfer operators will be needed to compute the interior near-field in each obstacle.

filter_operators = number_of_scatterers * [None]
transfer_operators = np.empty((number_of_scatterers, number_of_scatterers), dtype=np.object)

#The following will contain the left-hand side block operator
op = bempp.api.BlockedOperator(2 * number_of_scatterers, 2 * number_of_scatterers)

for i in range(number_of_scatterers):
    filter_operators[i] = .5 * identity_operators[i]- scaled_interior_operators[i]
    for j in range(number_of_scatterers):
        if i == j:
            # Create the diagonal elements
            element = scaled_interior_operators[j] + exterior_operators[j]
        else:
            # Do the off-diagonal elements
            transfer_operators[i, j] = bempp.api.operators.boundary.maxwell.multitrace_operator(
                grids[j], k0, target=grids[i])
            element = filter_operators[i] * transfer_operators[i, j]
        #Assign the 2x2 element to the block operator matrix.
        op[2 * i, 2 * j] = element[0, 0]
        op[2 * i, 2 * j + 1] = element[0, 1]
        op[2 * i + 1, 2 * j] = element[1, 0]
        op[2 * i + 1, 2 * j + 1] = element[1, 1]        

The following code assembles the right-hand sides.

rhs = 2 * number_of_scatterers * [None]
incident_trace_data = number_of_scatterers * [None]

for i in range(number_of_scatterers):
    incident_trace_data[i] = (
        bempp.api.GridFunction(op.domain_spaces[2 * i], fun=tangential_trace, dual_space=op.dual_to_range_spaces[2 * i]),
        bempp.api.GridFunction(op.domain_spaces[2 * i + 1], fun=neumann_trace, 
                               dual_space=op.dual_to_range_spaces[2 * i + 1]))
    rhs[2 * i], rhs[2 * i + 1] = filter_operators[i] * incident_trace_data[i]

In the following we visualize the near-field. The above code has computed the exterior trace data. But we also want to visualize the interior solutions. So we have to compute the interior trace data as well, which is done in the following code.

interior_trace_data = number_of_scatterers * [None]

for i in range(number_of_scatterers):
    interior_trace_data[i] = [np.sqrt(rel_permittivities[i]) * incident_trace_data[i][0],
                              np.sqrt(rel_permeabilities[i]) * incident_trace_data[i][1]]
    for j in range(number_of_scatterers):
        if i != j:
            efield, mfield = -transfer_operators[i, j] * (sol[2 * j], sol[2 * j + 1])
        else:
            efield, mfield = sol[2 * j], sol[2 * j + 1]
        interior_trace_data[i][0] += np.sqrt(rel_permittivities[i]) * efield
        interior_trace_data[i][1] += np.sqrt(rel_permeabilities[i]) * mfield

We now create a grid of plotting points in the $(\mathbf{x},\mathbf{y})$ plane and assign the indices in the sets associated with one of the obstacles or the exterior.

# Number of points in the x-direction
nx = 200

# Number of points in the y-direction
ny = 200

# Generate the evaluation points with numpy
x, y, z = np.mgrid[-2:2:nx * 1j, -2:2:ny * 1j, 0:0:1j]
points = np.vstack((x.ravel(), y.ravel(), z.ravel()))


# Compute interior and exterior indices

index = 0

ext_indices = np.arange(points.shape[1], dtype='uint32')[all_indices == 1]

For each scatterer we now evaluate the interior and exterior potentials on the associated points.

We now evaluate the bistatic radar cross section with the given incident angle. Here, we are only interested in backscattering into negative y plane. First, we define the evaluation points on the lower half of the unit circle. For the RCS we define the 0 degree angle to point into the negative x-direction, and correspondingly the 180 degree angle to be pointing into the positive x-direction.

number_of_angles = 400
angles = np.pi * np.linspace(0, 1, number_of_angles)
unit_points = np.array([-np.cos(angles), -np.sin(angles), np.zeros(number_of_angles)])

We now assemble for each scatterer the electric and magnetic far-field operators and evaluate the scattered field contribution for each of them. The assembly of the far-field operators will be done in dense mode as they are sufficiently small.

We now have everything together to plot the bistatic RCS.

plt.rcParams['figure.figsize'] = (10, 8) # Resize the figure

bistatic_rcs= 10 * np.log10(4 * np.pi * np.sum(np.abs(far_field)**2, axis=0))
plt.plot(angles * 180 / np.pi, bistatic_rcs)
plt.title("Bistatic RCS [dB]")
plt.xlabel('Angle (Degrees)')
