Waveguide Theory

Waveguide theory describes how electromagnetic waves, like light or radio signals, travel through specially designed structures called waveguides. These guides are typically hollow or solid channels that direct the energy efficiently with minimal loss. They work by confining the waves within specific dimensions, allowing controlled propagation at high frequencies, such as in radar or communication systems. The theory explains how the shape and size of the waveguide affect the behavior of the waves, including their speed and modes of transmission, enabling precise design for effective signal transmission over long distances or in complex environments.
