Abstract: A narrowband waveguide plasmonic Bragg grating based on metal-multi-insulator-metal configuration is proposed and investigated. The general dispersion relation in the vicinity of each ...
Abstract: A novel 3-D-metal-printing multibeam orbital angular momentum (OAM)-generating transmitarray with dual-layer I-slot grating metasurface in the frequency range of 19 GHz to 21 GHz is ...
