Waveguides waveguides are the most efficient way to transfer electromagnetic energy. Waveguides are essentially coaxial lines without center conductors. They are constructed from conductive material and may be rectangular, circular, or elliptical in shape. A waveguide is forming by adding quarter-wave sections shorted at one end on each side of a two-wire line. The lines become part of the walls of the waveguide, as illustrated in the following figure. The energy is then conducted within the hollow waveguide instead of along the two-wire transmission line

PROPAGATION OF RADIO WAVES

Propagation of waves propagation, radio is all about the transmission of radio waves from place-to-place without wires. Signals travel from the transmitting antenna to the receiving antenna in different ways depending on the frequency used. Some frequencies use the ionosphere to bounce signals around the world while other frequencies can only be used for line-of-sight operations
