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 ...

Rectangular waveguide is the most common type of transmission line used in microwave communication. It is a metallic transmission line ideally suitable for microwave frequencies and is employed to ...

"My former colleague at Penn State, Sven Bilén, is an expert in electromagnetics. I showed him some origami structures I'd been working on a few years ago. He was intrigued and asked if origami could ...

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 ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

The waveguide, a metal tube used to direct radio waves, is a critical component of satellites that enable communications. It is also one of the heaviest payloads that satellites transport into orbit.

The debuts follow a milestone year in 2025 where Lumus provided the waveguide for the Meta Ray-Ban Display AR glasses, demonstrating the optical performance and mass-manufacturability of geometric ...

Waveguides generate digital images directly in the field of vision and enable smart glasses such as the Meta Ray-Ban. We explain the technology behind them. Waveguides, as they are known in German, ...
