Modal Cutoff in Coaxial Transmission Lines of Conical and Cylindrical Geometries
Claude Weil, Billy F. Riddle, David R. Novotny, Robert T. Johnk
We present numerical data on normalized cutoff wavelength versus cone half-angle for the first three higher-order TEml modes, as well as four other modes of interest, in conical coaxial transmission lines (the co-conical line). These are given as a function of the ratio of outer-to-inner cone half-angles (proportional to line impedance) for outer ocne half-angles of 10 and 22.5 degrees. Results were compared to those for the coaxial transmission line of cylindrical geometry and found to be qualitatively similar.
