摘要: 将有限厚度及零厚度内导体板非对称横电磁波传输(ATEM)室主段划分为4个小区, 并在每个小区内根据边界条件把电势用特征函数展开, 利用点匹配法计算出ATEM室主段特性阻抗及横截面电势分布.由此计算出电场分布, 并绘出等值线及均匀区分布.

关键词: 电场分布, 特性阻抗, 横电磁波室, 点匹配法

Abstract: The section of an asymmetric TEM was divided into four regions and potential function is expressed as a Fourier series in each region.The point-matching was used on the boundary of these regions to determine coefficients of series.Thus, the characteristic impedance can be calculated and electric field obtained in terms of a potential function.

Key words: electric field, characteristic impedance, transverse electromagnetic cell, point matching method
