摘要：

Based on the generalized transmitting matrix (GTM) method to analyze the propagation characteristics of anisotropic media, the layered biaxial anisotropic media are analyzed. The state vector and coupling matrix of the transverse field in biaxial anisotropic media are constructed to obtain the eigenwave in biaxial anisotropic media. The GTM is introduced to obtain the reflection coefficient and transmission coefficient of layered biaxial anisotropic media. The angular and frequency characteristics of different dielectric coated structures are analyzed, and the numerical results are highly consistent with those of commercial software. Further, the electromagnetic propagation matrix is combined with the shooting and bouncing ray (SBR) method to obtain the electromagnetic scattering characteristics of the dielectric coated target. The root mean square error between the radar cross section results and the commercial software results is less than 3 dBsm, which reflects the accuracy of this method. © 2021, Editorial Office of Systems Engineering and Electronics.
