传播常数 meaning in English
propagation coefficient
propagation constant
propagation ratio
Examples
is the plane-wave propagation factor in the uppermost medium and w is the propagation factor of the surface wave. 是最上部介质中的平面波传播常数，而w是表面波传因子。 - < uk > is the plane - wave propagation factor in the uppermost medium and w is the propagation factor of the surface wave . < / uk >
< uk >是最上部介质中的平面波传播常数，而w是表面波传因子。 < / uk > - After simulation , it becomes more explicit on physical concept for solution process with the introduction of the wavenumber , and also more concise on solution
经过仿真计算，传播常数的引入不仅使问题的求解过程从物理概念上变得非常清晰，而且求解也更加简明。 - This antenna is a transmission line structure with propagation constant increasing from negative to positive values , providing the backward to forward scanning capability as frequency is increasing
这种天线基于传输线结构，其传播常数由负值增加到正值，显现出一种随频率增加而具有的由后向辐射变为前向辐射的特性。 - Then , according to waveguide theory , planar waveguide is analyzed . the main parameters , such as spread constant , decay coefficient , cut - off wavelength and so on , are deduced from dispersion formula of planar waveguide . the distributions of electromagnetic wave in the planar waveguide are obtained also
其次根据波导理论分析了平面波导，由平面波导的色散方程推导出了导模的传播常数、衰减系数、截止波长等特征参数以及波导中光波电磁场的分布。
