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 ...

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

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 have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Engineers have invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. They built photonic integrated devices that had ...

Co-packaged optics (CPO) technology can integrate photonic integrated circuits (PICs) with electronic integrated circuits (EICs) like CPUs and GPUs on a single platform. This advanced technology has ...

Holographic images: the two figures on the left are two holographic images produced by a leaky-wave metasurface at two different distances from the device surface. The other figures are distinct ...

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