Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

Waveguides function by confining electromagnetic waves within a structure, allowing them to travel with minimal loss of energy. This confinement is typically achieved through total internal reflection ...

A waveguide is a structure that guides waves, typically electromagnetic waves, along a specific path. It acts as a conduit for the waves, confining and directing them to travel in a controlled manner.

The propagation length can be maximized if the waveguide employs an asymmetric mode, which pushes a greater portion of the electromagnetic energy away from the guiding metal film and into the ...

Using electromagnetic waveguides on diamond-based chips, the researchers were able to generate magnetic fields large enough to change the quantum state of an atomic-scale defect in less than one ...

Waveguides are the pipes that direct and focus electromagnetic waves in telecommunications satellites and terrestrial devices like microwaves and phones. One of the most important components of ...

NRL researchers also developed 3D electromagnetic models of the waveguides. The modeling results provide a toolkit for designing future 2D devices that use slab waveguides.

Calculation: A representation of a network of electromagnetic waveguides (left) being used to solve Dirichlet boundary value problems. The coloured diagrams at right represent the normalized ...
