Abstract

A volume integral equation method given in terms of the equivalent electric and magnetic volume currents and discretized using non-conforming element-wise constant approximations is applied to electromagnetic scattering analysis of inhomogeneous and anisotropic objects. A broadband version of the multilevel fast multipole algorithm (MLFMA) combining low frequency stable planewave expansion technique with the high frequency MLFMA and utilizing global interpolators based on trigonometric polynomials is used to accelerate the computations.
