摘要：

In this paper, the finite-element boundary integral (FE-BI) method with UV method is applied to analyze the electromagnetic scattering from arbitrary three-dimensional bi-anisotropic objects located above a lossy half space. The form of electric field in bi-anisotropic materials is provided and cast into linear equations by finite element method (FEM), which is valid for any complex materials. The boundary integral equation (BI) is used to truncate the computational domain by using a half-space dyadic Green's function via the discrete complex image method (DCIM). A fast numerical approach, the UV method, is employed to decrease the memory requirement and the total CPU time for FE-BI solution. Numerical results are carried out so as to validate our developed algorithm. Further, the effects of different material parameters on the scattering characteristics of typical bi-anisotropic object in half space are examined and compared.
