Abstract:

A fast algorithm was proposed for the numerical computation of the electromagnetic scattering by multiple rectangular cavities embedded on an infinite ground plane, the algorithm can be used to compute the scattering problems with large cavities and high wave numbers. The numerical experiments confirm the effectiveness of our method.

Key words: scattering problem, Helmholtz equation, Fourier series
