In this paper, we propose and demonstrate a switchable terahertz metamaterial absorber
with broadband and multi-band absorption based on a simple configuration of graphene …

We propose and numerically demonstrate high Q-factor sensors based on all-dielectric
metasurfaces, which are very sensitive to the change of the refractive index of the …

The recent rise of active materials offers new opportunities for dynamically tunable
metamaterial devices. However, metamaterial devices with a dynamically switchable …

An actively reconfigurable broadband terahertz (THz) metamaterial functional device based
on the phase-change material vanadium dioxide (VO_2) and two-dimensional graphene …

Achieving absorption–transmission switchable devices is still a great challenge due to the
complex competitions among absorption, reflection, and transmission. Here, we propose a …
