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 ...

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 ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...

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.

Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These ...

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 ...
