Abstract
Abstract In this paper, an all-metal sectoral waveguide (SWG) mode converter has been proposed for TM01 to TE11 mode conversion, suitable for high-power application with high mode conversion efficiency and beam stability. Describing its operating principle, electromagnetic (EM) analysis has been carried out to observe the propagation behaviour in the different structure regions of the mode converter. A comprehensive design methodology, experimental investigation along with its beam stability performance has been presented. This design methodology has been typically demonstrated for 2.9–3.1 GHz frequency device; the performance of the designed device has been carried out using a commercial simulation code. To validate our design methodology and simulation, the results have been compared with experimental results and found in agreement. The proposed SWG mode converter has exhibited high conversion efficiency (98.4%) along with EM beam stability, suiting for the high-power applications.
期刊介绍：
The Journal of the Microwave Power Energy (JMPEE) is a quarterly publication of the International Microwave Power Institute (IMPI), aimed to be one of the primary sources of the most reliable information in the arts and sciences of microwave and RF technology. JMPEE provides space to engineers and researchers for presenting papers about non-communication applications of microwave and RF, mostly industrial, scientific, medical and instrumentation. Topics include, but are not limited to: applications in materials science and nanotechnology, characterization of biological tissues, food industry applications, green chemistry, health and therapeutic applications, microwave chemistry, microwave processing of materials, soil remediation, and waste processing.
