One dimensional sub-wavelength gratings, also known as metagratings have attracted
enormous attention due to the relatively simpler design configurations with versatile …

As a unique phase transition material, vanadium dioxide (VO 2) has been widely applied in
switchable and modulating metasurfaces. In this work, VO 2-based reflective meta-atoms are …

In this paper, we present a multi-functional terahertz metamaterial device based on the gold
and vanadium dioxide (VO_2). Availing of the phase transition characteristic of VO_2, the …

This paper proposes a vanadium dioxide metamaterial-based tunable, polarization-
independent coherent perfect absorber (CPA) in the terahertz frequency range. The …

In this paper, a low-profile metasurface retroreflector based on an ultra-thin wide-angle and
high-efficiency metalens is proposed and investigated. Owing to its stable high transmission …

The mid-infrared spectral range is critical for bio-sensing and gas detection. Existing
methods for designing wavelength-selective absorbers involve two-dimensional (2D) and …

An acoustic metagrating (MG) constructed with an inverse-design scheme can be used to
realize anomalous reflection, but its efficiency is limited. In this work, we find that the …

Conventional metasurfaces cannot adjust the electromagnetic responses once the
structures are determined. In this paper, we numerically demonstrate a thermally switchable …

Based on the phase transition characteristics of vanadium dioxide (changes in conductivity
with temperature), we designed a dynamic metasurface for wavefront manipulation that can …

Metasurfaces have made great progress in the past decade in generating various planar
optical devices. However, most metasurfaces exhibit their functions in either reflection mode …
