Abstract The use of low-emissivity (low-e) materials in modern buildings is an extremely efficient way to save energy. However, such materials are coated by metallic films, which can strongly block radio-frequency signals and prevent indoor-outdoor w

We report on the design, fabrication, and characterization of low-loss antireflection (AR) structures for Si windows in 10–30 THz. Based on scattering-matrix simulations and effective medium theory, optimal Si filling ratios are presented for AR st

Metamaterials are artificial structures which exhibit fascinating properties unreachable by traditional materials. Here, we report on the design, fabrication, and characterization of acoustic metasurfaces consisting of dead-end channels coiled in a 2

Based on analytic formulas and numerical simulations, we investigate the enhancement effect of dielectric antireflection coatings on the performance of quantum-well infrared photodetectors (QWIP) with Au grating couplers and operating at 15 μm. It i

When a charged particle moves close and parallel to the surface of a Babinet metasurface composed of metallic $C$-aperture resonators, strong electromagnetic radiation arises at resonant frequency. Here we systematically study the Smith-Purcell effec

Based on analytic formulas and numerical simu- lations, we propose a plasmonic cavity with a top Au grating and bottom Au film to enhance quantum-well infrared pho- todetectors (QWIPs) operating at wavelengths between 2 and 30 μm. By using plasmonic

Perfect sound absorbers with a deep-subwavelength thickness are important to applications such as noise reduction and sound detection. But their absorption bandwidths are usually narrow and difficult to adjust. A recent solution for this problem reli
