Radar cross section of a system of conducting spheres each coated with a dielectric layer

Abstract

Analytical solution to the problem of scattering of a plane electromagnetic wave by an array of conducting spheres each coated with a dielectric layer is derived. The incident, scattered and transmitted electric and magnetic fields are expressed in terms of the vector spherical wave functions. The vector spherical translation addition theorem is applied to impose the boundary conditions on the surface of each dielectric‐coated sphere. Numerical results are computed and presented graphically for the radar cross of several configurations of dielectric‐coated spheres.
