摘要 提出一种新的半解析方法,分析并计算了非对称横电磁波传输室谐振频率,通过计算等效为终端开路和短路的非均匀传输线的谐振频率计算了非对称横电磁波传输室谐振频率.采用矩量法计算了中间过程的电容分布和沿传输线的特性阻抗.通过解传输线阻抗转移公式和终端输入阻抗的气隙电容表达式的联立方程得出了数值结果. A simple semi-analytical method is presented.It calculates the resonance frequency in asymmetric transverse electromagnetic cell by estimating the resonance frequencies of equal inhomogeneous transmission line with open circuit and short circuit at end. The moment method was used to calculate the capacitance of cross-section, then characteristic impedance along line was obtained. The numerical results were obtained in a table by solving the combined equation of transmission line impedance transfer equation and terminal input impedance expression in gas capacitance.
