Abstract :
A new and unifying approach is presented for the analysis of plane-wave scattering by metal-strip gratings with a complex permittivity to account for their finite conductivity. A new set of metal modes is discovered, and the method of mode matching is employed for the formulation of the boundary-value problem. The effect of grating conductivity and thickness on the scattering characteristics are systematically examined, including the current distribution and power absorption within the metal strips.<>
