Liquid Crystal Leaky-Wave Antennas With Dispersion Sensitivity Enhancement
TL;DR: In this article, a liquid crystal (LC)-based beam-scanning leaky-wave antennas (LWAs) with extra dispersion sensitivity enhancement (DSE) components are introduced to increase the slope of effective phase constant versus frequency of LWAs and, hence, the beam scanning range.
Journal ArticleDOI
Electrically tunable terahertz wave modulator based on complementary metamaterial and graphene
TL;DR: In this article, an electrically controllable light-matter interaction in a hybrid material/metamaterial system consisting of an artificially constructed cross cut-wire complementary metamaterial and an atomically thin graphene layer to realize terahertz (THz) wave modulator was demonstrated.

TL;DR: In this paper , a Fourier-based metaprocessor for analog computing on a single-layer Huygens' metasurface has been proposed, where basic mathematical operations, including differentiation and cross-correlation are performed by directly modulating complex wavefronts in spatial Fourier domain.
Journal ArticleDOI
A low-loss electromagnetically induced transparency (EIT) metamaterial based on coupling between electric and toroidal dipoles
TL;DR: In this paper, an effective approach to construct a low-loss metamaterial by incorporating an electric toroidal dipole response into electromagnetically induced transparency (EIT) effect has been proposed, which is numerically and experimentally demonstrated.
