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 ...

Electromagnetic (EM) waveguides are ubiquitous devices in spacecraft, naval, electrical, and communication systems to deliver microwave energy from their inlets to outlets 1. Most EM waveguides are ...

Smart glasses vendor Even Realities on Wednesday released two new products meant to work together: the Even G2 Display Smart Glasses and the Even R1 Smart Ring. The G2 glasses are the antithesis of ...

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 ...

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.

Several RF and microwave radiating devices, such as horn antennas, Fabry–Perot cavity antennas, and aperture-fed focusing devices, are excited through rectangular waveguides. The impedance matching of ...

One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites ...

ABSTRACT: A broadband feeding technique for the uniplanar tapered slot antenna (TSA) is presented. The TSA operates at a center frequency of 6.5 GHz with a 7 GHz bandwidth (107 percent). The antenna ...
