摘要

本文研究了基于有限元法(FEM)的非线性特征分析算法在太赫兹工作结构中的性能和行为。引入了一种类似于树-共树分裂的公式方法来抑制非物理解，提高了数值稳定性和效率。采用了精确的全局网格截断技术，对开放结构的特征分析进行了改进。

A Finite Element eigenanalysis of electrically large THz and photonic structures

In this work the performance and behavior of nonlinear eigenanalysis algorithms on formulation based on the Finite Element Method (FEM) is investigated for structures operating in THz. A technique like the tree-cotree splitting formulation method for the suppression of non-physical solution, the enhancement of the numerical stability and efficiency, is incorporated. Accurate global mesh truncation techniques are also adopted and refined for the eigenanalysis of open structures.
