Integrated waveguide
An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum. Common types of optical waveguides include optical fiber waveguides, transparent dielectric waveguides made of plastic and glass, liquid light guides, and liquid waveguides. Optical waveguides are used as components in integrated optical circuits or as the transmission medium in local and long-haul optical communication systems. NettetSubstrate integrated waveguide (SIW) is an new form of transmission line that has been popularized in the past few years by some researchers. New transmission lines only come along once in a lifetime, so pay …
