ELectromagnetic Scattering from an Arbitrarily Shaped Three-dimensional Inhomogeneous Bianisotropic Body
This paper presents a numerical solution to scattering problems that involve 3D inhomogeneous bianisotropic scatterers of an arbitrary shape. The constitutive relations are assumed to be of the most general form and composed of four 3×3 matrices or tensors. The problem is described through a mixed potential formulation. The effectric and magnetic potentials are related to effectric and magnetic bound charges and polarization currents and then to the effectric and magnetic polarizations. The effectric field and magnetic field integral equations are constructed. The method of moments technique is then applied to obtain a numerical solution to the problem. The volume of the scatterer is meshed by tetrahedral cells and face-based functions are applied to expand unknown quantities. The proposed formulation has been evaluated and verified through examples of scattering by various chiral and gyrotropic scatterers illuminated by a plane effectromagnetic wave. Numerical results of scattering from a chiroferrite sphere are also presented showing the flexibility of the proposed method.
