Waveguide

A waveguide is a physical structure that directs and guides electromagnetic waves, such as radio or microwave signals, from one point to another. Think of it like a tunnel that confines and directs these waves, preventing energy from spreading out. Waveguides are commonly made of metal or dielectric materials and are used in radar, satellite communications, and microwave technology, ensuring efficient transmission with minimal signal loss. They are essential in controlling high-frequency signals where traditional cables are less effective, providing precise and reliable guidance for electromagnetic energy.
