This paper describes the heating properties of the proposed RF capacitive type multi-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. The RF capacitive type applicator using one pair of electrodes has been in practical use. However, hotspots appear in fat layers, it is not easy to heat deep-seated tumors with one pair of electrodes. We have proposed a heating method using two pairs of electrodes. In the present study, the proposed heating method was discussed with computer simulation results using 3-D FEM and experiment results. From these results, it was found that the proposed heating method was useful to heat deep-seated tumors.
