Frequency Response of Impedance Screens of Finite Thickness in the Resonance Band

Abstract

Technique for computing electromagnetic waves scattering by well conducting non-closed screens of finite thickness is considered. This technique is based on employing the E-field integral equation that takes into consideration approximate surface impedance boundary conditions (SIBC). Results are presented of radar cross section (RCS) computation for spherical screens given various values of their conductivity and thickness and various wave lengths in the resonant scattering range.
