The Scattering Analysis of Complex Structure based on Fast Finite Element Method
A high order vector finite element method to analyze the scattering of complex structure is considered. The solution of large sparse complex linear system equation is the most memory and time consuming part of the finite element method (FEM). In order to solve the scattering problems by FEM efficiently, we use Krylov subspace iterative method to solve the FEM matrix and further introduce the p-type multigrid preconditioning method as the preconditioner of the iterative method. Finally, some numerical examples are presented to show the reliability and efficiency of the method in this paper.
