DOI: 10.1103/physreva.110.l061503
Abstract: We present a theoretical study on photonic topological crystals whose symmetry is governed by quantum valley-Hall topological insulators and whose propagating edge modes are strongly confined due to bowtie geometries. Dielectric bowtie structures exploit the… read more here.

DOI: 10.1109/lawp.2025.3630134
Abstract: In this letter, a metasurface-based high-aperture-efficiency transmitarray antenna (TA) is proposed. To improve the feeding efficiency, a rectangular waveguide cavity-backed slot array was adapted for the feed. Eight coupling slots (CSs) corresponding to the unit… read more here.
