首先,在球坐标系下,通过德拜位函数得到均匀各向同性介质中矢量波动方程的解。然后,分析了内、外向波的单界面和多层界面的反射和透射,得到了相应的反射系数和透射系数以及广义反射系数和透射系数。接着,推导了δ源在球形分层介质中的不同位置产生的德拜位。最后,根据得到的德拜位,用球坐标系下的矢量波函数表达出场点在不同位置时的电并矢格林函数和磁并矢格林函数。 First of all, in the spherical coordinate system, the solution of the vector wave equation in a homogeneous isotropic medium is obtained by Debye bit function. Then, the reflection and transmission of the interface between single and multi-layer are analyzed, and the corresponding reflection coefficient, transmission coefficient and generalized reflection coefficient and transmission coefficient are obtained. Then, the debye position of δ source at different positions in spherical layered media is deduced. Finally, according to the Derby bit obtained, the electric dyadic Greenwich function and the magnetic dyadic Greenwich function when the field points are in different positions are expressed by vectorial wave functions in the spherical coordinate system.
