Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

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
