Numerical calculation of analytic solutions for higher order modes in conical lines

This article presents a full analytical study of higher order modes in conical transmission lines. Full analytical field solutions and modal cutoff equations are included, and methods for the evaluation of these solutions are presented which combine a number of mathematical techniques and results. Calculated numerical results and field distributions of some higher order modes in conical lines are shown. © 2008 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2009.
