Fitting Green’s Function FFT Acceleration Applied to Anisotropic Dielectric Scattering Problems

Abstract: A volume integral equation based fast algorithm using the Fast Fourier Transform of fitting Green’s function (FG-FFT) is proposed in this paper for analysis of electromagnetic scattering from 3D anisotropic dielectric objects. For the anisotropic VIE model, geometric discretization is still implemented by tetrahedron cells and the Schaubert-Wilton-Glisson (SWG) basis functions are also used to represent the electric flux density vectors. Compared with other Fast Fourier Transform based fast methods, using fitt… Show more

“…Furthermore, similar to FGG, ROF only projects the original Green's function onto the nodes of the reduced order grid, and the ultimate computation error mainly comes from the fitting method. The independence of basis functions makes ROF applicable to compute scattering from complex dielectric body by combining surface or volume integral equation [18].…”
