Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.
Abstract: This work describes wide-incident-angle radio-wave absorbers for millimeter-wave (mmW) and sub-terahertz (sub-THz) applications. A loop-shape frequency-selective surface (FSS) is employed to ...
Abstract: Design of wide-angle frequency-selective surface (FSS) absorbers is significantly challenging as the impedance in free space varies substantially with the incidence angle. To enhance the ...
