Scattering by a Perfectly Electromagnetic Conducting Random Grating
Saeed Ahmed, Fazli Manan

An analytic theory for the electromagnetic scattering from a perfectly electromagnetic conductor (PEMC) random grating is developed, using the duality transformation which was introduced by Lindell and Sihvola. The theory allows for the occurrence of cross-polarized fields in the scattered wave, a feature which does not exist in standard scattering theory. This is why the medium is named as PEMC. PEMC medium can be transformed to Perfect electric conductor (PEC) or perfect magnetic conductor (PMC) media. As an application, plane wave reflection from a planar interface of air and PEMC medium is studied. PEC and PMC are the limiting cases, where there is no cross-polarized component.
