The AM-L4 rectangular-waveguide termination, which incorporates forced-air cooling as standard, enables it to offer a higher power-handling capability than convection-cooled alternatives. It suits ...

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 ...

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.

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, ...
