Scattering by multilayer isorefractive elliptic cylinders

An analytical solution to the plane-wave electromagnetic scattering by multilayer elliptic cylinders is derived in the case of isorefractive materials. For these materials, a recursive solution similar to the solution for the multilayer circular cylinder is obtained. Moreover, it will be shown that the matrix-based recursive procedure for common dielectrics reduces to the present solution in this particular case. Finally, a number of numerical examples and comparisons will be provided.
