Banded waveguide synthesis

Banded waveguide synthesis is a technique used in the field of optics and photonics, specifically in the design and fabrication of waveguides. A waveguide is a structure that guides electromagnetic waves, including light, and is used in various applications, such as telecommunications, sensors, and optical circuits. In banded waveguide synthesis, the concept typically refers to the design of waveguide structures that are optimized for specific wavelength ranges—often referred to as "bands.
