Paper Abstract

Flux of electromagnetic radiation is attenuated on propagation through a metal grid disposed on a substrate. The magnitude of extinction is a combination of the total scattering and surface plasmon absorption, which is predicted by the Mie theory adapted to the case at hand. Experimental measurements over a wide wavelength range conducted using a metal grid on a sapphire window support the calculations. Further analyzed is the electric field generated in the wire mesh, treated by the Drude-Lorentz theory. While the analysis and data show that the attenuation across a window covered by a wire mesh is consists of a combination of the Fresnel and Mie losses, a considerable plasmon field is generated in the wire.
