In this paper, a novel p-FFT method based on characteristic basis function method (CBFM) has been proposed and implemented to solve electromagnetic scattering by large scaled finite periodic arrays. The CBFs can be constructed by solving the integral equations associated with one unit cell at plane wave incidence from different incident angles and with different polarizations. Then, the unit cell...
This paper presents two parallel schemes of fast algorithms based on the parallel FFT. In the first scheme, the parallel FFT is applied to speed up multiplication of the impedance matrix and a vector directly. In the second scheme, the AIM is parallelized. To demonstrate the efficiency of the parallel schemes, electromagnetic scattering by a very large cylindrical wire array and a conducting sphere...
Scattering of a plane wave by a plasma anisotropic spherical shell is considered in this paper and scattered fields are obtained in spherical coordinates. The electromagnetic fields in a plasma medium and in a free space are expanded in terms of the spherical vector wave functions (SVWFs) for a plasma anisotropic medium and the SVWFs in an isotropic medium. Numerical results for very general properties...
