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 ...

This article evaluates some of the strengths and weaknesses of reflective and diffractive waveguides used in augmented reality (AR) optics for smart glasses. Waveguides are the optics used in smart ...

"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." ...

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 ...

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 ...
