Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology

Advanced Photonics Research, EarlyView.
This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Mitigating Losses in Hyperbolic Asymptotic Eigenmodes

Advanced Photonics Research, EarlyView.
Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced.
