Abstract

The Drude model is used to describe the equivalent relative permittivity of metal, which varies the frequency and determines the value of the surface impedance. The surface integral equation method is applied to solve electromagnetic scattering by arbitrarily shaped three dimensional metallic objects modeled with the impedance boundary condition (IBC). Several metal spheres are analyzed which are composed by three different metals. The computed results are all compared with the perfect electric conductor (PEC) case, which show that there are big differences of the electromagnetic properties for different metals.
