Excitation of the rectangular cavity with a set of horns for uniform microwave heating

Abstract

The stationary (harmonic) excitation of the rectangular resonator with an absorbing dielectric layer on the lower wall several rectangular horns located on the top and side walls has been considered. With the end walls of the cavity it is possible the conveyor feed of dielectric product, for what is absorbing filter loaded with absorbers and prevent the exit of energy from the resonator. The filter impedance is modeled by an absorbing impedance wall. Besides the presence of perfect reflecting walls for modeling of microwave processing with a single time product download is considered. The simulation of excitation by horns is produced by a given field. The fields in the discloses are represented as fields H10-wave of the respective waveguides, the amplitude of which is associated with the power of the sources (magnetrons). These exciting fields are modeled as magnetic surface currents. The task allows to carry out the optimization, whereas optimization packages such as HFSS involves substantial computational costs.
