Abstract The electromagnetic aspect of microwave dielectric heating is analyzed. It is concluded that a re-entrant cavity may supply high electric field component that is theoretically favorable efficient microwave absorption process in a small liquid or solid chemical sample. A re-entrant cavity has been designed using both finite difference time domain and finite element time domain methods and constructed with a PC-driven control and power supply unit. The field distribution in the sample as well as Q-values for a water-loaded cavity are calculated and measured. Good agreement between designed and measured quantities were found. |
