Paper Abstract

We study theoretically the transmission of p- and s-polarized light through a thin, supported, silver or gold film, both of whose surfaces are one-dimensional, periodically corrugated surfaces, as a function of the wavelength of the incident light. The calculations are carried out by the use of reduced Rayleigh equations in the form of a pair of coupled inhomogeneous matrix equations for the amplitudes of the scattered and transmitted Bragg beams. The results show that enhanced transmission occurs for both p- and s-polarized incident light for large-amplitude periodic corrugations of the two surfaces. In p polarization an additional enhancement occurs at the wavelengths of the surface plasmon polaritons supported by the film. Thus, slits that pierce the film are not necessary for enhanced transmission of light through it.
