The Design of a Switchable Infrared Hybrid Plasmonic Metasurface Absorber for Energy Harvesting Applications

摘要

A plasmonic switchable polarizationinsensitivemetasurface absorber is proposed. The designprovides two modes of operation by employing phasechangematerial in semiconductor and metallic phases.In this paper, we study the switchable absorptionbehavior of the metasurface operating in a dual-bandand single-band modes targeting the mid-infrared rangesuitable for energy harvesting applications such asthermophotovoltaics. The design is optimized using aglobal optimization technique.
