Abstract :
The attenuation coefficient of a corrugated rectangular waveguide is determined by the power-loss method, using approximations previously found to be successful. An error in earlier predictions by other workers is corrected, and the region identified in which the corrugated waveguide exhibits an attenuation advantage over comparable smooth-wall rectangular waveguide. However, the comparable circular corrugated waveguide is shown to be superior.
