Radiation of Electric and Magnetic Dipole Antennas in Magnetically Anisotropic Media

摘要

The numerical calculation of the solution of Maxwell equations satisfies the energy conservation law. Numerical computation shows that time average value energy flux on a surface of sphere from a point dipole remains independent from its radius. As shown in the electric dipole directional diagrams, medium becomes isotropic for such radiator if its moment is directed along anisotropy axis. The dipole pattern in isotropic media is shown in Fig. 1 and directional diagram itself possesses the rotation symmetry. However the point magnetic moment does not possess such property.
