以单轴各向异性介质球为例,得出了各向异性介质张量在球坐标系中的表达式,得到了特征波矢量的表达式;研究了散射场、透射场各向异性系数随介电常数张量、方位角等因素的变化规律,所得结果与有关文献一致。
The monoaxial medium sphere is taken as an example,the analytical expression of its medium tensor and the corresponding eigenwave numbers both in the spherical coordinate system are obtained.The variations of the anisotropic coefficients in the scattering field and the transmission wave versus medium tensor and azimuth angle etc.are researched.The results obtained in the paper are in agreement with that in the literature and establish a theoretical base for the anisotropic target’s identification and concealing.
