DOI: 10.1142/s0217984919502014
Abstract: Ultra-narrowband light absorption is desired for many applications. A near-infrared TM-polarization (magnetic field is parallel to grating grooves) ultra-narrowband absorber with dielectric metamaterials has been reported theoretically in this paper. The simulation results show that… read more here.

Abstract: Vanadium oxide (VOx) microbolometers enable the construction of high-performance yet low-cost and uncooled imaging detectors in the mid-infrared spectrum. Typical micro-bolometers are broadband sensors with no polarization selectivity. Thus, imaging detectors based on microbolometers have… read more here.
