摘要

本文依据微波网络理论及网格波阻抗的概念,对时域有限差分(FDTD)计算中的非均匀网格反射波进行分析,提出了网格网络分析和综合的概念,分析了网格网络的反射特性,给出了网格网络的综合过程.基于上述理论和概念,在一维(TEM波)和三维微带结构以及方波导中实现了有关的非均匀网格的网络特性,其特性可用于沿传播方向的网格非均匀性的匹配,减小网格反射波及改进波的传播特性等.

Abstract

In this paper,according to the theory of microwave network and the concept of mesh wave impedance,the wave reflection of non-uniform mesh for FDTD technique is analyzed,and the concept of analysis and synthesis of mesh network is presented.The reflecting characteristic of mesh network is analyzed first.Then the procedure of synthesising a mesh network is deduced.On the basis of the above theory,network characteristics of non-uniform mesh,which can be used to match non-uniform mesh or improve the transmitted characteristic for a mesh wave to travel along the non-uniform mesh etc.,are realized in 1-D (TEM wave),3-D microstrip structures and waveguide.
