Huygens metasurfaces have demonstrated remarkable potential in perfect transmission and
precise wavefront modulation through the synergistic integration of electric resonance and …

Exploring flexible electronics is on the verge of innovative breakthroughs in terahertz (THz)
communication technology. Vanadium dioxide (VO_2) with insulator-metal transition (IMT) …

We investigate transient, photo-thermally induced metasurface effects in a planar thin-film
multilayer based on a phase-transition material. Illumination of a properly designed …

We present the design of an asymmetric metasurface made of germanium antimony
tellurium nanowires that supports quasibound states in the continuum. A fully coupled …

We present and numerically verify a functionally hybrid dual-mode tunable polarization
conversion metasurface based on graphene and vanadium dioxide (VO_2). The tunable …

Vanadium dioxide () is a favorable material platform of modern optoelectronics, since it
manifests the reversible temperature-induced insulator-metal transition (IMT) with an abrupt …

VO2 is a promising phase change material offering a large contrast of electric, thermal, and
optical properties when transitioning from semiconductor to metallic phase. Here we show …

The photonic spin Hall effect (PSHE) can manifest as the spin-dependent splitting
(perpendicular to the plane of incidence) of a light beam, ie, transverse beam shift …
