Modern satellites rely on electromagnetic waveguides—hollow structures that carry high-power signals between components such ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

High-powered satellites use electromagnetic waveguides to deliver energy from one component to another. Typically, they are made of heavy, inflexible metal tubes with an even heavier flange on either ...

(Nanowerk Spotlight) The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent ...

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, ...
