Abstract

Analytic expressions of the dyadic Green's function of an arbitrary electric current source embedded in a general biisotropic sphere are presented at first, and the radiation characteristics of an electric dipole antenna placed on the surface of a biisotropic sphere lens are examined. The effects of the electric-and the magnetic-coefficients (ξ e and ξ m ) of biisotropic medium on the radiation patterns of electric dipole antenna are investigated in detail.
