Waveguide
In space and astronautical engineering, a waveguide is a structure that is used to guide electromagnetic waves. It is typically made of metal and is designed to confine and direct the waves as they travel through it. Waveguides are commonly used in satellite communication systems, radar systems, and other applications where the transmission of electromagnetic waves is necessary. They are particularly useful in space applications because they are able to transmit signals over long distances without significant loss of signal strength. Waveguides come in a variety of shapes and sizes, including rectangular, circular, and elliptical, and can be designed to operate at different frequencies. They are an important component of many space-based systems and are critical to the success of many space missions.
