Abstract: Negative reflection and negative refraction are exotic phenomena that can be achieved by platforms such as double-negative metamaterial, hyperbolic metamaterial, and phase-discontinuity metasurface. Recently, natural biaxial van der Waals (vdW) materials, which support extremely anisotropic,… read more here.

Abstract: Phase gradient metasurfaces (PGMs) have demonstrated powerful capacities for manipulating light waves freely. However, PGMs have limitations of bulky size and narrow bandwidth that hinder further applications. In this work, we present the design and… read more here.

Abstract: When water waves are reflected by a rigid boundary, classical Snell's law dictates that the incident and reflected waves should lie on opposite sides of the surface normal. However, phase gradient metasurfaces/metagratings (PGMs) can overcome… read more here.

DOI: 10.1080/17455030.2019.1651462
Abstract: We show the existence of negative reflection and negative refraction in a slab of biaxial absorbing medium In4Se3 placed between two isotropic media. We find the limiting angle of incidence in the ... read more here.
