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 ...

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 ...

High-speed optical circuits and sensors generally require strict control over light polarization to minimize loss and cross-talk in photonic devices such as waveguides. An A*STAR team now predicts ...

A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high ...

Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...
