AN EFFICIENT VECTOR FINITE ELEMENT METHOD FOR FULL-WAVE ELECTROMAGNETIC FIELD SIMULATION

摘要

A vector finite element method is widely used for full-wave electromagnetic field simulation. In this report several methods of increasing VFEM efficiency are considered: implementation of lumped elements and ports in order to decrease matrix dimension, automatic choice of moments number in a fast frequency sweep process and specially developed preconditioned iterative solvers to improve convergence of the problem. Results of each method implementation are given and its advantages are discuused.
