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 ...

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 ...

Holographic photopolymers can be cast onto and around other optical elements, then patterned with a 3D routed waveguide to form hybrid integrated photonics. While multi-photon initiation can be used ...

Researchers have now developed a new superior hardware platform for artificial intelligence accelerators using photonic integrated circuits on silicon chip. Co-packaged optics (CPO) technology can ...

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 ...

Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in ...
