TM01 Mode Transducer Using Circular and Rectangular Waveguides
This article presents a modal based analysis technique to excite TM01 mode in circular waveguide from a rectangular waveguide propagating the dominant TE10 mode. This mode transducer includes rectangular waveguide to coaxial line transition through a door-knob probe and coaxial to circular waveguide transition. Modal analysis has been carried out considering oversized circular waveguide supporting higher-order modes like TE21. TE01 and TM11 modes apart from the desired mode TM01. Simulated and experimental data are presented. (C) 2010 Wiley Periodicals, Inc Int J RF and Microwave CAE 20 259-263, 2010
