“…On the other hand, when ⃗ is a half SWG, the inner integral of ( 12) and ( 14) includes one triangular surface integral in ordinary VIE model; however the inner integral becomes the sum of four triangular surface integrals in anisotropic VIE model. If the superscripts " " and " " mean "full SWG function" and "half SWG function," respectively, according to different combinations of full and half SWG basis functions, there exist four types of matrix elements for anisotropic VIE model: (6) .…”

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 fitting Green’s function technique has higher accuracy and can be applied to a relatively coarse grid, so the Fast Fourier Transform of fitting Green’s function is selected to accelerate anisotropic dielectric model of volume integral equation for solving electromagnetic scattering problems. Besides, the near-field matrix elements in this method are used to construct preconditioner, which has been proved to be effective. At last, several representative numerical experiments proved the validity and efficiency of the proposed method.
