Abstract

The aim of this paper is to present the efficient implementation of the multipoint greedy model order reduction approach, which is used for fast three-dimensional frequency-domain electromagnetic analysis by means of the finite element method. The efficiency and accuracy of the proposed approach is highlighted by the numerical examples, which aim to compute the wide frequency-band scattering parameters of the two bandpass microwave filters and dielectric resonator antenna.

贪婪多点模型降阶技术在微波结构快速宽带频率分析中的高效实现
本文的目的是提出多点贪婪模型降阶方法的有效实现,该方法可用于有限元法的三维频域电磁快速分析。通过计算两个带通微波滤波器和介质谐振器天线的宽带散射参数,验证了该方法的有效性和准确性。
