Abstract

Discusses the implementation of the multilevel fast multipole algorithm (MLFMA) for solving the hybrid integral equation of electromagnetic scattering. Tetrahedron volume cells are used to discretize the material region, and triangle patches are used to represent the conducting surfaces. This selection provides accurate and flexible representation for any complex object shapes. Due to a reduction of the computational complexity, the method presented in this paper can be applied to solve electromagnetic scattering problems with electrically larger dielectrics.
