Smart glasses come in more forms than most people realize. After reviewing more than 20 pairs, I'm breaking down what's out ...

Abstract: We present the design of rectangular waveguide excited metasurfaces for near-field shaping using a coupled dipole framework. Waveguide-fed metasurfaces are array-like radiating systems ...

"Because the most common electromagnetic waveguides are rectangular-shaped, our origami designs needed to maintain a rectangular cross section in the operational state for comparable performance." ...

Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These ...

Abstract: Specifications for the waveguide (including aperture dimensions, frequency range, cutoff frequency, etc.) are given in this standard. This standard considers the tolerances of the waveguide ...

Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in ...

For the system noise temperature calibration of the K/Q/W triple-band cryogenic receiver on Tianma Radio Telescope (TMRT), a design of W-band eight-hole waveguide directional coupler is proposed in ...

Based on the book series by Holly Jackson, the Netflix series is a British murder mystery with a greener-than-usual detective. By Margaret Lyons What teen girl doesn’t dream of solving her first ...

5G base stations rely on phased arrays to steer signals and increase data rates. Beam steering circuits, however, consume power. Using waveguides could reduce energy consumption in base stations.

Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...
