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." ...

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 ...

Researchers have now developed a new superior hardware platform for artificial intelligence accelerators using photonic integrated circuits on silicon chip. Co-packaged optics (CPO) technology can ...

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 ...

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 ...

The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State University, has discovered slab waveguides based on the two-dimensional material hexagonal boron nitride. This milestone ...

A team of researchers has made a breakthrough discovery in the world of Beyond 5G/6G (B5G/6G) signal transmission. Taku Nakajima and Kazuji Suzuki of Nagoya University in Japan, along with their ...

Researchers fabricated 20mm length waveguides made of the superconducting metal niobium (right). It shows improved conductivity compared with normal metal materials such as a gold-plated tellurium ...
