Abstract
Based on the conservation of electromagnetic energy, a theoretical model of equating the electromagnetic anisotropic medium to the electromagnetic isotropic medium is established. The correctness of this proposed model is verified, and how to use the model is presented. The equivalent permittivity of an anisotropic medium cylinder is researched by using the proposed model. It is found that the equivalent permittivity increases with the increase of the volume of the cylinder, and the electromagnetic mechanism of this phenomenon is presented. The analytical expression of the scattered field of an anisotropic cylinder being irradiated by a plane electromagnetic wave with a general direction is studied. It is found that the geometrical size of the finite length and the angle between the electromagnetic wave propagation direction and the symmetry axis of the cylinder have a great effect on the scattering of the anisotropic medium cylinder.
