Abstract

A unified formulation for the scattering from objects in the resonance and intermediate frequency regions is presented in terms of integral operators arising from the electric and magnetic field integral equations (EFIE and MFIE) of Maxwell's equations. The boundary conditions for a wide class of conducting and permeable scatterers are expressed in terms of coupled Fredholm equations. These equations are solved by the method of moments (MM) technique for rotationally symmetric bodies with ka 30, where a is the characteristic dimension of the body. Generalizations of these solutions for coated bodies with various anisotropies are presented. The solutions are applicable to bodies that are in part concave, convex, and with voids. The results, obtained for the backscatter and bistatic cross sections using these methods, are compared with those obtained by the extended boundary condition method, the finite element method, or measured experimentally.
