Waveguides are hollow metal tubes used to transfer energy from one point to
another. The energy travels slower in a waveguide than in free space.

Copper losses can result from power (I2R) loss, in the form of heat, or skin
effect. These losses decrease the conductivity of a line.
Dielectric losses are caused by the heating of the dielectric material between
conductors, taking power from the source.
fields of a conductor being dissipated into space or nearby objects.
A transmission line is either electrically long or short if its physical length is
not equal to 1/4λ for the frequency it is to carry.
Lumped constants are theoretical properties (inductance, resistance, and
capacitance) of a transmission line that are lumped into a single component.

Distributed constants are constants of inductance, capacitance, and
resistance that are distributed along the transmission line.
