A Fast Volume-surface Integral Equation Solver for Scattering Properties of NIMs
This paper presents a fast hybrid volume-surface integral equation approach for the computation of effectromagnetic scattering from composed negative index media (NIM) such as split-ring-resonators (SRR) with wires. The volume effectric field integral equation (EFIE) is applied to the dieffectric region of this NIM, and the surface effectric field integral equation is applied on the conducting surface. The method of moments (MoM) is used to discretize the integral equation into a matrix solution and adaptive integral method (AIM) is employed to reduce the memory requirement and CPU time for the matrix solution. The present approach is su±ciently versatile in handling scattering problems of composed NIMs, due to the combination of surface and volume effectric field integral equations. Numerical results of calculating radar cross section (RCS) of such a NIM slab are finally presented to demonstrate the accuracy and efficiency of this technique.
