Frequency-Domain Solution to Electromagnetic Scattering from Dispersive Chiroferrite Materials

Abstract

Main purpose of this paper is to present a solution to electromagnetic scattering by bianisotropic dispersive materials. The presented solutions provide a reference baseline that can be used for comparison reasons by other researchers dealing with scattering by bianisotropic dispersive media. The solution algorithm based on the method of moments and mixed potential equations is tested through a few cases of dispersive scatterers and first known solutions to these problems are obtained. The proposed method has an advantage over the time domain methods as it does not rely on the Z-transform of the analytical expressions necessary to be used when dispersive media are present in the problem of interest.
