Abstract

Abstract: A new algorithm based on the infinite element-partial basic solution vectors domain decomposition
method(IEM-PBSV-DDM) is presented for solving electromagnetic scattering problems of electrically large cylinders. The
infinite element method is introduced to truncate the computational space, which decreases the number of unknowns on each
subdomain and the number of nodes on the interface boundaries significantly. The partial basic solutions of the nodes on the
interface boundaries of contiguous subdomains are solved in advance, and then the original solution could be trivially
obtained by a simple vector summation procedure. Compared with the traditional method, the presented method can reduce the
computation time and memory requirement greatly.

Key words: domain decomposition method, infinite element method, electromagnetic scattering
