Abstract :
In this paper, the calculation of scattering from cavities coated with bianisotropic media is carried out using higher-order finite element-boundary integral (FE-BI) method. A required variational formulation for the FE-BI matrix equation is presented for scattering problem of the cavity with an infinite ground plane and filled with general bianisotropic media. The higher-order tetrahedral elements are applied to expedite the convergence of the FE-BI solution
