摘要

本文提出了一种改进的、有效的有限差分频域格式扫频方法。利用模型阶约简技术减少描述整个分析结构的方程数量，然后对角化。对每个频率点的大矩阵进行耗时昂贵的反演，可以用一个小的对角矩阵与向量的简单乘法来代替。所提出的快速扫频方法也可用于包含宏模型的FDFD。

Fast frequency sweep based on the model order reduction technique for calculating scattering parameters in FDFD

The paper presents an improved, efficient method of the frequency sweep for the Finite Difference in Frequency Domain scheme. The number of equations describing the entire analyzed structure is reduced with the Model Order Reduction technique and then diagonalized. Time-expensive inversion of large matrices for each frequency point is substituted by a simple multiplication of a small, diagonal matrix by a vector. The presented fast frequency sweep can also be used for the FDFD containing macromodels.
