Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

open access: yesAdvanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

open access: yesAdvanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

open access: yesAdvanced Photonics Research, EarlyView.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...
