Abstract
Average power-handling capability of beam waveguides limited by the maximum temperature rise in phase correcting devices due to power dissipation within them is determined by solving the equation of heat conduction. Both the reflector guide and the lens guide are considered in detail. Simple formulas for estimating the average power-handling capability can be derived when the reflectors and the lenses are thin compared with the spot size of the beam.
It was found that the reflector guide is much more suitable for high power transmission of microwave energy than the lens guide considering the power-handling capability. Forced air cooling is effective in raising the average power-handling capability of the reflector guide.
