Abstract

In this paper, analysis and discussion of electromagnetic scattering from objects coated with arbitrarily magnetized lossy ferrite materials are carried out by using the hybrid vector finite element method and multilevel fast multipole algorithm. For a coated cube as an example, the impact of anisotropy properties controlled by magnetized ferrite materials on the scattered field characteristics is considered. Numerical results show that the strength and direction of the biased magnetic field strongly affect the backscattered field
