Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
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

A plasmonic reflective filter utilizing monolayer graphene is proposed and theoretically examined. The filter demonstrates dual‐band reflection and absorption characteristics at resonance wavelengths in the near infrared. The reflection dips is adjusted by manipulating the chemical potential of graphene.

The images (a) and (b) illustrate a composite metamaterial with anisotropic permittivity. When incident light, polarized in transverse magnetic or transverse electric modes, enters the structure, the reflectance spectra in (c) and (d) show low reflection and high absorption over a wide range of incidence angles. This behavior has potential applications

This work introduces a humidity‐modulated strategy to regulate the dynamic transition from quasi‐BICs to BICs based on the symmetry‐breaking in geometry and permittivity for the hybrid photonic‐plasmonic asymmetric gratings. It proves that it is a promising approach for dynamic regulating optical properties and applied in fabricating various micro ...

A pair of Sb2Te3 topological insulator (TI) nanotips is fabricated by using the focused ion beam lithography to demonstrate the plasmonic hot spot effect at the visible range. The strong enhancement of electric field can be generated on the TI nanotips due to the plasmonic effect, giving rise to the obvious improvement of photoluminescence emission ...
