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 ...

Theoretical Investigation of the Sensitivity—Q Trade‐off in Terahertz Graphene Metamaterial Sensors via Interdigitated Design and Complex‐Frequency Waves

open access: yesAdvanced Sensor Research, EarlyView.
A dual strategy combining interdigitated graphene resonators and complex‐frequency waves yields a 54‐fold Q$Q$‐factor enhancement and superior sensitivity, establishing a high‐FOM platform for ultrasensitive terahertz biosensing. ABSTRACT Terahertz (THz) technology holds great promise in biomedical imaging, non‐destructive testing, biosensing, and ...
