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 ...

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 ...

Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...

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, ...

If you’re in the market for a new set of hi-fi speakers or studio monitors, you might have come across the term ‘waveguide’ before. You might’ve seen a photo or illustration in marketing materials ...

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.
