List 7 components in the waveguide system?

A waveguide system typically includes the following components: 1) The waveguide itself, which is the structure that directs the electromagnetic waves; 2) Power sources, such as lasers or microwave generators, that produce the waves; 3) Couplers, which connect the waveguide to other components or systems; 4) Terminations, which absorb or reflect energy at the end of the waveguide; 5) Filters, which selectively allow certain frequencies to pass; 6) Amplifiers, which boost signal strength; and 7) Sensors, which detect and measure the characteristics of the waves within the system.
