This research investigates the plane-wave scattering from a two-dimensional rectangular cavity embedded in an infinite metallic surface that has been covered with a dielectric material. The transverse magnetic and transverse electric polarizations are both considered. The rectangular geometry of the embedded cavity allows for the use of a Fourier based solution. Presented here are modifications to the Fourier solution due to the addition of the material layer above the metallic surface. Applying these modifications allows for a solution to be determined for the electric and magnetic fields at the cavity aperture, where the strength of the return echo is then calculated and displayed in a radar cross section. In addition, an alternate method is introduced to improve upon the speed that it takes to determine a solution, providing a close approximation to the actual results.
