Metamaterial-Based Energy Harvesting for Detectivity Enhanced Infrared Detectors

Wide‐band polarisation‐independent metasurface‐based carpet cloak

“…Metasurfaces, which are two‐dimensional version of metamaterials [20–23], are able to apply abrupt changes of phase, amplitude, and polarisation, to the incident wave [24–27]. This ability of metasurfaces has been used in different applications such as increasing efficiency of thin film solar cells [28, 29], developing flat lenses [30], designing photonic topological insulators [31], and enhancing absorption in infrared detectors [32]. Also at microwave regime, metasurfaces have found different applications including polarisation conversion [33], scattering manipulation [34], radar cross‐section (RCS) reduction [35], beam splitting [36], and metasurface‐based antennas [37].…”
