SCATTERING BY PEMC CYLINDER COATED WITH POROUS SAND

Abstract

The electromagnetic scattering of an incident uniform plane wave from a circular PEMC cylinder covered with porous sand is investigated theoretically. The research takes into account polarization situations that are both parallel and perpendicular. A comparison is made with the sand-coated cylinder's back scattering cross-section. The monostatic and bistatic echo widths for the co-polarized and cross-polarized fields have been computed for a number of PEMC cylinders covered with porous sands. For the specific cases of PMC (perfect magnetic conductor) (Mηc=0) and PEC (perfect electric conductor) (Mηc=∞), echo widths have been computed and compared to the PEMC coated cylinder. Compared to similarly coated PEC and PMC cylinders, the coated PEMC has a smaller radar cross-section (RCS). A comparison between the numerical results and the available literature reveals a high degree of agreement.
