This paper describes the heating properties of the proposed multiple RF capacitive applicators for deep tumor hyperthermia treatments. Hyperthermia is a method of cancer treatment based on the clinical fact that cancer cells are more sensitive than normal tissue in the temperature range of 42-43 degrees Celsius. They can be killed by one hour repetitions of one hour heating. The RF capacitive applicator has been in practical use. However, it is not easy to heat deep-seated tumors with one pair of electrodes. Hotspots develop in fat layers, because of the edge effects of the electrodes. We have proposed a heating method using multiple RF applicators. The proposed heating method, which uses two pairs of electrodes, was discussed with computer simulation results for temperature distributions using 3-D FEM. From these results, it was found that the proposed heating method was useful to heat deep-seated tumors.
