Characterization and Modeling of a Microwave Reactor for the Open-Loop Control of its Impedance

In the context of controlling a microwave chemical reactor, this article presents an approach to address the reflection of electromagnetic waves caused by impedance mismatch. Microwave chemistry is a technique that has a lot of advantages compared to conventional methods, but its major drawback is the reflection of EM waves by the microwave cavity. One of the ways to overcome this problem is to use a triple stub tuner and adjust it according to the impedance of the reaction medium. In this manuscript, a numerical model that characterizes the system as well as simulation results of the model are shown, in addition to experimental results to validate the proposed model. De-embedding and the cascade methods have been adopted in this work which show promising results to address the energy transfer problem.
