论文摘要
本文在球形几何形状中涉及不同的图像定理，即爱的等效原理，归纳等效原理和物理光学等效原理。图像定理近似的偏差是通过比较从图像近似获得的电磁场与球形几何学的精确电磁场之间的模态膨胀系数来量化的。两种不同的方法，即通过球形添加定理和二元格林函数方法的矢量电位方法进行分析。球形成像定理的应用包括金属镜设计和其他电物体散射。
This paper deals with different image theorems, i.e., Love's equivalence principle, the induction equivalence principle and the physical optics equivalence principle, in the spherical geometry. The deviation of image theorem approximation is quantified by comparing the modal expansion coefficients between the electromagnetic field obtained from the image approximation and the exact electromagnetic field for the spherical geometry. Two different methods, i.e., the vector potential method through the spherical addition theorem and the dyadic Green's function method, are used to do the analysis. Applications of the spherical imaging theorems include metal mirror design and other electrically-large object scattering.
