Perturbation solution of surface impedance to the scattering problems
Abstract
A perturbation solution is developed for considering the scattering problem of plane wave by an arbitrarily-shaped imperfectly conducting scatterer, whose equivalent surface currents are expanded as a Taylor series of surface impedance. The approximate boundary conditions expressed by the surface impedance are used for the surface. The electric field integral equation (EFIE) and magnetic field integral equation (MFIE) are employed to solve the scattered fields.
