Abstract:
1. A frequency selective infrared (IR) rectenna having a predetermined frequency band, the frequency selective IR rectenna comprising: a frequency selective surface plasmonic (FSSP) structure designed to selectively convert radiation in the predetermined frequency band that is incident on the FSSP structure into surface plasmon waves (SPWs) substantially independent of the angle of incidence of the incident radiation on the FSSP structure, the FSSP structure having: an electrically insulating thin film layer coupled to the second surface of the FSSP structure; an electrically insulating via layer coupled to the electrically insulating thin film layer opposite from the FSSP structure, the electrically insulating via layer including a plurality of vias running approximately perpendicular to the second surface of the FSSP structure, each via positioned to correspond to a peak of a SPW standing wave pattern formed by SPWs at the design SPW resonance propagating on the second surface of the FSSP structure; a plurality of via conductors, one via conductor formed in each of the plurality of vias in the electrically insulating via layer; and an electrode electrically coupled to the plurality of via conductors.
