Abstract: Abstract A metasurface consisting of three layer H-shaped arrayed structures is proposed. Numerical simulation and experiment results demonstrate that our scheme can realize mutual polarization conversion and multi-band diode-like asymmetric transmission for linearly polarized waves… read more here.

Abstract: In this paper, a three-layered chiral metamaterial is proposed to achieve broad dual-band and high magnitude asymmetric transmission (AT) in near-infrared communication band for circularly polarized waves. The asymmetric parameter reaches to 0.9/0.86 at 174/235… read more here.

DOI: 10.1364/oe.452180
Abstract: Structuring elements of gratings brings more freedom in manipulating diffraction waves, e.g., retroreflection using diffraction orders other than the 0th order. Most retroreflective metagratings (RMs) can achieve retroreflection only under one particular direction, limiting their… read more here.

DOI: 10.1364/oe.453058
Abstract: Impedance mismatch generally exists upon interfaces between different media. This is especially true for TE-polarized waves with large incident angles since there is no Brewster effect. As a result, high-efficiency transmission can only be guaranteed… read more here.
