Design of Rectangular Waveguide-fed Metasurfaces for Near-Field Shaping using a Coupled Dipole Model
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 ...
I hope you like the look of the Wayfarer-style Meta Ray-Ban glasses, because the Meta Ray-Ban Display is more of the same. The plastic frames (available in black or sand) have the same rectangular ...

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 ...
