Abstract :
Efficient analysis of electromagnetic scattering from three-dimensional, perfect electrically conducting, multiscale structures in a half space is conducted in this paper. The half-space dyadic Green´s function is adopted as the kernel of the electric field integral equation so that the unknowns are only associated with the surface of the scatterers. A recently developed Calderon preconditioner is adopted to significantly improve the ill-conditioning of the matrix due to the multiscale nature of the structures. The kernel-independent multilevel adaptive cross approximation is further implemented to accelerate the computation and reduce the memory requirement. Numerical examples are presented to demonstrate the effectiveness of this method for analyzing multiscale structures situated in a half space.
