摘要：

The dyadic Green's function (DGF) method is an attractive approach for the calculation of electromagnetic scattering in spherically symmetric layered geometry. We investigate a recent formulation and reveal a problem that is associated with the nonconverging series that are employed for the calculation of the DGF in unbounded media. To overcome this deficiency, we introduce a new formulation that gives the desired solution analytically. The new technique combines operations on scalar Green's function with a rotation of the coordinate system. Our formulation also accelerates the algorithm to evaluate the DGF in spherically multilayered media. We present examples where we compare the conventional formulation with our new one.
