The Design of a Switchable Infrared Hybrid Plasmonic Metasurface Absorber for Energy Harvesting Applications
Keywords:energy harvesting, metasurface, plasmonic, polarization-insensitive, switchable
A plasmonic switchable polarizationinsensitive metasurface absorber is proposed. The design provides two modes of operation by employing phasechange material in semiconductor and metallic phases. In this paper, we study the switchable absorption behavior of the metasurface operating in a dual-band and single-band modes targeting the mid-infrared range suitable for energy harvesting applications such as thermophotovoltaics. The design is optimized using a global optimization technique.
