Scattering analysis of mixed metallic/uniaxial objects using surface integral equations accelerated by adaptive cross approximation algorithm

In this paper, a MoM solution accelerated by the ACA algorithm is presented to analyze electromagnetic wave interactions with complex 3D objects consisting of metallic and uniaxial anisotropic components. The problem has been formulated using the PMCHWT equations for homogeneous anisotropic media and EFIE for conducting surfaces. The ACA algorithm is applied to accelerate the matrixvector multiplication in the iterative solution. Numerical results are presented to illustrate the good performance of the proposed algorithm.
