Abstract
We apply a mode expansion technique to the three-dimensional vectorial diffraction problem of an electromagnetic field that is incident on a perfectly conducting, metallic disc containing a pattern of rectangular pits. The mode expansion technique reduces the three-dimensional diffraction problem to a two-dimensional numerical problem. Furthermore, by choosing a particular numerical discretization, the
