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 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 ...

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, ...

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 ...

Lumus, the pioneering developer of geometric (reflective) waveguide technology for augmented reality (AR) eyewear, today unveiled its wide field of view ZOE and optimized Z-30, two new waveguides that ...

High-performance geometric waveguides deliver industry-leading brightness, clarity, and ergonomics for clinical workflows. NESS ZIONA, Israel, Nov. 12, 2025 /PRNewswire/ -- Lumus, the pioneering ...

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.

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...
