色散媒质 meaning in English
dispersive medium
Examples
- Then , the auxiliary fields fdtd is used to the periodic structure made of dispersive material , such as the pyramid absorbers in anechoic chamber . the permittivity vs frequency property of the absorber is approached by some dispersive equation model , such as debye model and lorentz model , so the broadband response of the absorber can be gotten through one calculation
然后将辅助场fdtd应用到色散媒质周期结构中，导出了色散媒质中的迭代式，并以暗室吸波材料阵列为例进行计算，提出用某一类型的介电常数色散函数(如debye型、 lorentz型等)来逼近材料的介电常数频率特性的方法，从而可以对吸波材料进行一次性宽频计算。 - In specific , the formulation of the rcwa for 2 - d and 3 - d metallic gratings and the formulation of the fdtd method for dispersive media are presented . a novel hybrid diffraction method , which is based on the kirchhoff - huygens diffraction formula and the rcwa , is proposed to simulate the working of a planar integrated diffraction grating
