Abstract

The procedure for the resonant frequencies detection in a cylindrical metallic cavity, based on transmission characteristic, is presented in this article. An analysis of procedure efficiency to resonant modes identification is conducted numerically and experimentally verified. As a numerical tool, TLM time-domain method, enhanced with the wire compact model to account for the presence of feeding and monitoring probes, is used. Also, in terms of modes identification and resonant frequency dependence of probe length, results of transmission procedure are compared with corresponding previously published results of reflection procedure [J. Jokovic, B. Milovanovic, and N. Doncov, Int J RF Microwave CAE 16: 346–354, 2006.]. © 2008 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2008.
