Abstract :
In this paper, an Nth order approximate eigenequation of circular groove guide is presented. Using the sixth order approximate results, some propagation properties of the TE/sub 11/ mode of circular groove guide are recalculated. The results are more accurate than before and in good agreement with the measurements.
