tem wave meaning in Chinese

横电磁波

However the magnitude of the longitudinal components is less than 1 % of the transverse field , when the size of cpw ' s is very small . so we can approximately consider the field in cpw ' s as tem wave
但是在一定条件下(主要是减小导带宽度) ，场的纵向分量很小，共面波导中的电磁场可近似看大连海事大学博士学位论文成是tem波。
The numerical method based on the coupling of the finite difference method in time domain with the discrete fast fourier transform is applied to calculate the first four eigenfrequencies and eigenfunctions of the six - cavity with open boundary . the absorbing boundary condition for tem wave is tested numerically , and it is applied to writing the code . the cold testing of the cavity is done and the results are good agreement with the numerical results
计算x波段六腔开放腔前四个模式的场分布;根据第二章公式分别计算x波段六腔开放腔前四个模式的电子负载电导并总结了这四种工作模式渡越效应的规律，基于这种小信号理论分析了x波段渡越辐射振荡器，得到了工作模式及可能产生的模式竞争。
