Abstract
The parametric Fourier Modal Method is extended to the case of lamellar gratings that are periodic in two directions. We provide numerical evidence that improved convergence rates can be obtained. As an example, we calculate the optical transmission of a gold grating and rather good agreement with Ebbessen's experimental data is observed.
