Abstract

In this paper, electromagnetic (EM) scatterings from electrically large Perfect Electric Conductor (PEC) and Perfect Magnetic Conductor (PMC) targets coated with Uniaxial Electric Anisotropic Medium (UEAM) layer are evaluated and compared. The effect of the coating layer’s parameters including εu, εv and the thickness (d) are studied. It is shown that radar cross section (RCS) of a PMC with UEAM coating is less than that of PEC with the same coating. In some cases, about 20 dB reduction in RCS has been obtained for UEAM coated PMC plate.
