Open publisher page 0 citations

Abstract

Waveguide-attenuation expressions given in the literature disagree by as much as 0.2%, which exceeds the precision customarily associated with waveguide computations. In addition, the UK DEF standard waveguide-attenuation expression is shown to be misleading. A rectangular waveguide is specifically treated and standard waveguide-attenuation expressions are suggested.
