Abstract :
Based on the electric field intensity and magnetic induction intensity of electric dipole & electric quadrupole, and the power density of magnetic dipole and electric quadruple in magnetic anisotropic medium, the radiation power of electric quadrupole in magnetic anisotropic medium can be achieved in anisotropic spherical coordinate system by spherical surface integration. By coordinate transformation, the radiation power of electric quadrupole in rectangular coordinate system are obtained. The theoretical results indicate that the radiation power is correlative with magnetic conductivity of the anisotropic medium. Our results offer a theoretical basis for measuring the radiation power of electric quadrupole in magnetic anisotropic medium.
