Em wave scattering by perfectly conducting disk of finite thickness

Calculation technique for modeling of scattering characteristics for perfectly electrically conducting (PEC) disk of finite thickness is proposed. Employed algorithms are based on solving surface integral equations (IE) of the 1^st and 2^nd kind. The results of radar cross section (RCS) calculation for discs with various thicknesses are compared with exact results for infinitely thin disc. The backscattered radiation patterns of thin disc in E- and H-planes are presented.
