基于多分辨分析的时域与频域相结合的微带线特性分析

The Multiresolution-Based Combined Time/FrequencyDomain Method for the Analysis of Microstrip lines

本文以数值模拟基片各向异性微带线色散特性为例，给出了一种改进的基于多分辨分析理论的数值分析波导特性的方法。这种方法的特点是巧妙地将时域分析和频域分析有机地结合起来，避免了纵向开放边界条件的处理，减少了内存需求及运算工作量。其精度与类似的FDTD相当，但计算时间可以减少近一半。

Abstract: A modified numerical computation technique based on multiresolution analysis (MAR) is presentedin this paper for solving waveguide characteristic problems. As a computational example the microstrip lines withanisotropic substrate are numerically simulated by this technique. The main advantage of the proposed technique isto combine the time-domain and frequency-domain analysis subtly. It needn't consider open boundary condition andefficiently reduced the memory requirement. The computational time of the presented method is approximately halfthat of the corresponding conventional FDTD method with similar accuracy.
