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 …

Surface plasmon polaritons (SPPs) and their low-frequency counterparts (ie, spoof SPPs on
artificial surfaces) have recently found numerous applications in photonics, but traditional …

We demonstrate plasmonic color printing with subwavelength resolution using circular gap-
plasmon resonators (GPRs) arranged in 340 nm period arrays of square unit cells and …

We propose a spoof surface plasmon polariton (SPP) emitter which is composed of ultrathin
corrugated metallic strips, exhibiting the directional radiation property. The spoof SPP …

Transmission line is a basic component in all passive devices, integrated circuits and
systems. Microstrip is the most popular transmission line in the microwave and millimeter …

We present a bifunctional polarization converter based on Dirac semimetals (DSMs) and
vanadium dioxide (VO_2), which consists of two layers of DSMs on both sides, a metal …

By directly incorporating a sub-wavelength amplifier chip into the spoof plasmonic resonator,
the quality (Q) factor of the original passive resonator has been significantly increased by …

In the terahertz (THz) band, it is a challenge to integrate multiple functions into a very small
unit cell structure of metasurface. However, the hybrid metasurfaces composed of several …

In this work, the simultaneous realization of circular‐to‐linear polarization conversion (PC)
and electromagnetically induced transparency (EIT) is theoretically reported in terahertz …

In this paper, a reflective multi-band and dual-functional terahertz wave polarization
converter based on a metasurface is proposed. The unit cell of the proposed metasurface …
