Resonances on metallic compound transmission gratings with subwavelength wires and slits

Mostrar todas las versiones(2)

We investigate the response of gratings formed by subwavelength wires in a dielectric medium. For gratings with a single wire per period, most of the incident power is transmitted through the structure. If the distance between adjacent wires is small enough, the excitation of waveguide modes can lea...
