equivalent admittance meaning in English

等效导纳

Kc of each higher mode in ridge waveguide is a very important parameter , once kc is obtained , the wavelength , phase constant , phase velocity , waveguide wavelength , equivalent reactance , equivalent admittance and so on can be obtained simply . then ridge waveguide devices can be designed based on these paremeters . in view of the widely use of ridge waveguides , the research of kc is very important in practice
由于脊波导中主模及各高次模的kc是一个很重要的参数，求出了kc ，可以很简单地求出、相移常数，相速、波导波长、等效电抗、等效导纳等等，求出这些参数后就可以用各种方法设计脊波导元器件了。
Abstract : the optical admittance of a single - layer film is derived from the characteristic matrix of the film pile . based on the single - layer , recurring layer by layer , supercomposing one by one , deriving the equivalent admittance of the film pile and calculating the reflect coefficient of the amplitude , the reflectivity and transmissivity of hte whole film system is derived at last
文摘:根据膜堆的特征矩阵，求出单层膜的光学导纳，在单层膜的基础上，进行层层递推，叠加起来，求出膜堆的等效导纳，计算振幅反射系数，最后求出整个膜系的反射率、透射率。
