Abstract

In this paper, a novel idea of reducing numerical complexity of finite difference method using multiple macromodels is presented. The efficiency of the macromodeling technique depends on the number of ports of a model. To enhance the efficiency of the algorithm the field samples at the boundary of the macromodel are replaced with amplitudes of discretized Legendre polynomials. Redefining the problem in such manner results in significant reduction of the analysis time. The validity and efficiency of the proposed procedure are demonstrated by performing the analysis of two microwave filters requiring a high density mesh.
