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 ...

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.

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 ...
