Abstract

This paper presents an augmented volume integral equation (VIE) method to solve electromag- netic scattering from objects with generalized electric and magnetic anisotropy. The method is derived from the 3D vector wave equation for both electric and magnetic fields and considers both the permittivity and permeability of the scatters as generalized 3 by 3 tensors. The moment method scheme is presented and edge basis functions are used to discretize the induced electric and magnetic field distributions inside the objects. Numerical results show that the proposed method does not only solves the scattering problem of generalized anisotropic objects, but also has better accuracy and convergence for the permeability term compared to the VIE method presented in the authors' previous work.
