Resonance property of an optoelectronically reconfigurable infinite periodic array of densely spaced subwavelength slots

Abstract

This paper theoretically presents TM electromagnetic plane wave scattering characteristics of an optically controlled subwavelength slot grating with an electrically small period on a dielectric slab. It is theoretically disscussed about how the resonance property of the subwavelength slot grating could be controlled using photoinduced plasma, changing the thickness of the slots, for application of the subwavelength slot grating to the optoelectronically reconfigurable millimeter wave circuits.
