Narrow gaps for transmission through metallic structured gratings with subwavelength slits

Mostrar todas las versiones(2)

Transmission dips in the response of metallic compound gratings formed by several wires and slits in each period have been recently reported for normal illumination. These anomalies are generated by a particular arrangement of the magnetic field phases inside the subwavelength slits, and they are ch...
