Optomechanical Devices and Sensors Based on Plasmonic Metamaterial Absorbers
… magnify light-matter interactions. Optical absorbers based on plasmonic metamaterials can absorb light resonantly at the operating wavelengths with up to 100% efficiency. We have explored plasmonic absorbers at infrared wavelengths for thermal detectors, e.g. a gold nanostrip antenna …

Aluminum nitride microelectromechanical infrared detectors with integrated metamaterial absorbers
… detectors based on the seamless integration of metamaterial (MM) structures with microelectromechanical (MEMS) AlN resonators. Historically, uncooled absorbers have been limited in two key metrics: selectivity, the ability to distinguish distinct wavelengths of incident light, and sensitivity, …

Effect of Nanoparticle Shape on the Response of Broadband Metamaterial Absorbers in the Visible Spectrum
Optical metamaterials are defined as structures with electromagnetic properties in the visible spectrum that are unique and not present in nature. An example of such a metamaterial is a Metal-Insulator-Metal (MIM) structure, which is composed of: (i) a gold meta-surface layer on the top, (ii) …

Acoustic metamaterials comprised of dead-end pores and black hole effect for low frequency sound absorption in linear and nonlinear regimes
… aim of this work is to design and test acoustic metamaterial absorbers particularly for mitigation of low frequency sound of high intensity. The absorbers designed are formed of a series of plates with a central perforation, separated by air cavities. Two types of structures are investigated: the …

Vanadium Oxide Microbolometers with Patterned Gold Black or Plasmonic Resonant Absorbers
High sensitivity uncooled microbolometers are necessary to meet the needs of the next generation of infrared detectors, which seek low power consumption and production cost without sacrificing performance. Presented here is the design, fabrication, and characterization of a microbolometer with …
