Calculation of scattering characteristics of anisotropic coated targets based on SBR method

In this paper, the propagation characteristics of anisotropic media are analyzed based on the layered model and generalized propagation matrix (GTM) method. Using the state vectors and coupling matrices of transverse fields in anisotropic media, GTM is introduced to obtain the reflection coefficients and transmission coefficients of layered anisotropic media, and the reflection coefficients of anisotropic media coated with a metal substrate are further deduced by using the ideal metal boundary conditions. The numerical calculations of the reflection coefficients of the multilayered anisotropic media are highly consistent with the results of commercial software. The electromagnetic propagation matrix is combined with the shooting and bouncing ray method (SBR) to obtain the electromagnetic scattering characteristics of the coated target.
