NUMERICAL ANALYSIS OF HIGH FREQUENCY CHARACTERISTICS OF COAXIAL CORRUGATED WALL WAVEGUIDE
同轴波纹波导的高频特性数值分析

A novel numerical modeling technique, based on FD-TD and the intrinsic characteristic of spatial periodic structure, is used to analyze the high frequency characteristics of the slow wave structure of arbitrary geometry. The method was sucessfully applied to calculate the complete dispersion relation and couple impedance of TMon modes in a coaxial corrugated wall waveguide.
