Based on the fact that the conductivity of photosensitive semiconductors can be regulated by
external pump light, a metamaterial absorber with single-band and dual-band switchable in …

Achieving actively tunable metamaterial absorption is a significant development direction.
Phase-transition materials have attracted growing interest for the use in nanophotonics …

In the study of modern optics, the work of terahertz metamaterial absorbers is mostly multi-
band perfect absorbers and ultra-wideband perfect absorbers. In contrast, in practical …

In this paper, a tunable ultra-broadband terahertz metamaterial absorber is proposed based
on the phase transition material of vanadium dioxide (VO 2). The absorber cell consists of a …
