TIME-HARMONIC TWO-AND THREE-DIMENSIONAL CLOSED FORM GREEN'S DYADICS FOR GYROTROPIC, BLANISOTROPIC, AND ANISOTROPIC MEDIA

摘要

The time-harmonic Green's dyadics are studied for homogeneous media con-sisting of complex bianisotropic media which are characterized by gyrotropic material dyadics. First the spatial Fourier transform with respect to the preferential axis of these Green's dyadics is calculated in closed form. Then it is shown that it is possible to calculate the inverse transform in closed form when the material parameters satisfy two conditions. These closed form three-dimensional Green's dyadics comprise several known closed form Green's dyadics as special cases.
