    Abstract

    Experiments have been conducted on a part-shaped microwave applicator to characterize microwave heating behavior. Microwave energy is induced in a brass cavity through several ports via external microwave applicators tuned to the TE011 mode. An iris, acting as a shunt admittance device, is placed between the external applicator and the part-shaped mold. The objective of this study is to determine the effect of the iris orientation, configuration, and width on the heating patterns and heating rates in non-reactive, glass-reinforced polyester plates. As suggested from thermal paper images and initial heating rates, the iris width controls the intensity of the admitted electric field (E-field) from the external applicator; the resonant heating patterns appear to be independent of the iris width. The TE011 mode is most easily excited using a single iris oriented parallel to the microwave excitation probe. Utilizing an asymmetric single iris at an off-centered port improved heating uniformity. Preliminary calculations of the E-field inside the part-shaped cavity qualitatively depict similar resonant patterns to those of experimental results.
