Application of the measured equation of invariance to the scattering problems of an anisotropic medium cylinder

The measured equation of invariance (MEI) is first successfully applied to analyze the EM scattering problem of an anisotropic medium cylinder. A rectangular terminated boundary loop is used to limit the infinite region scattering problem of an anisotropic cylinder to a finite region boundary value problem, and the rectangular region is discretized by a rectangular mesh. A generalized finite difference equation for inhomogeneous anisotropic medium is first derived and which are used at interior nodes. At the terminated boundary nodes, the MEI is applied. For some special cases, the numerical results are in good agreement with the MoM solutions. The numerical results for a ferrite cylinder show that the RCS can be effectively controlled by adjusting the parameters of the ferrite medium.
