摘要

The heating characteristics of a radio frequency rectangular resonant cavity applicator excited by various antennas are investigated for use in hyperthermic treatment. The coupled electromagnetic and heat-transfer equations are solved to obtain the heating characteristics. Two types of antennas and three types of dielectric phantoms are used in the calculations and measurements. Clear differences in the heating characteristics are observed for these phantoms and antennas. Previously, we were only able to heat up the surface or end regions of the phantom, while it is now possible to uniformly heat up the deeper regions with the current applicator. Therefore, this applicator is suitable for hyperthermic treatment.
