Analysis of electromagnetic field distributions in a 915 MHz single-mode microwave applicator

Abstract

The electromagnetic field distributions in the waveguide of a 915 MHz single-mode microwave sintering applicator equipped with a loading pressure system were simulated using a JMAG-Studio program. The disturbance in the magnetic field as well as in electric field was caused by the insertion of the alumina loading pressure system due to reflection effect of alumina. However, the separated magnetic field and electric field maxima can be obtained by adjusting position of the alumina loading pressure system in the waveguide. The simulation results were evaluated by comparison with experimental measurement.
