Abstract

A microwave resonant cavity with rectangular section used as catalyzer for chemical reactions is presented, operating at the center frequency of 2.45 GHz, where two parallel metallic walls of the cavity are replaced with perfect magnetic conductors (PMC). This choice allows to obtain a uniform electric field distribution in each transversal section of the designed cavity, improving the power transfer to the fluid, if compared with the resonant cavity with electric walls. Moreover, the number of the tubes containing the reagent solution, can be significantly increased per surface unit. The cavity resonator has been designed using CST Microwave Studio, a commercial general purpose software for the electromagnetic simulation of three-dimensional high-frequency components.
