equivalent admittance
Examples
- 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。 - An attempt is made to use the filled function as the modified function approach to apply global optimization to optical thin film problems . it is proved successful when applied to problems such as antireflection coatings and beam spliters . meanwhile , it is also found that when the number of layers is fixed those local minima with less total optical thickness appear to be better . in the realization . needle method are made to explore the impact of local optimization methods used , parameter of these methods , the starting design , the search accuracy of function and the methods of thickness growth
从理论分析来看,由于光学薄膜的特性是由在入射介质那一侧的等效导纳所确定的, needle方法把等效导纳作为状态变量,把每一层的折射率作为控制变量,运用最优控制的原理计算出在薄膜内部每一个厚度对应的点上折射率改变所引起的评价函数的改变,由此选取改变折射率后评价函数变化最大(评价函数变小)的那一点进行插入。 - 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
