Abstract

A high‐order vector finite‐element‐method (FEM) analysis of periodic absorbers is presented. By the virtue of the FEM, accurate modeling of complicated absorber structures is made possible. For a given accuracy, high‐order elements are used to reduce the number of unknowns and hence the computing time and memory consumption. The FEM is further combined with the asymptotic waveform evalaution (AWE) technique to produce fast‐frequency sweep. Both singly and doubly periodic absorbers are modeled and the accuracy of the method is demonstrated by comparisons with analytical solutions and published data. © 2003 Wiley Periodicals, Inc.

An efficient renumbering method for high-order finite element models is presented. The method can be used to reduce the profile and wavefront of a coefficient matrix arising in high-order finite element computation. The method indirectly performs node renumbering and involves three main steps. In th
