Electromagnetic Modeling of an Adaptable Multimode Microwave Applicator for Polymer ProcessingAbstract
This paper presents the electromagnetic modeling of a novel adaptable multi-feed multimode cylindrical cavity applicator where the spatial distribution of the electric field can be specified a priori to accomplish a desired processing task. The electric field intensity inside the cavity can be tailored by just varying the power delivered to each port, and the mode-switching can be realized without mechanically adjusting the cavity dimensions. An orthogonal feeding mechanism is developed to reduce the cross coupling between the ports. Numerical simulations are performed for the cavity applicator to verify the theoretical analysis.
