Abstract

The radiation of an arbitrarily oriented Hertzian dipole placed at the center of an anisotropic sphere is analyzed. Using Fourier analysis, the dyadic Green's function is computed in terms of the convenient spherical vector wave functions. The unknown reflected and scattered fields inside and outside the anisotropic sphere are expressed by employing Fourier series and spherical vector wave functions series, respectively. The unknown expansion coefficients are determined through the implementation of the boundary conditions at the sphere surface, using the method of moments. Numerical results are computed and presented for several anisotropic materials and sphere dimensions. >
