Evaluation of a semi-cylindrical solenoid as an applicator for radio-frequency hyperthermia

A modified solenoid having a semicircular cross section is evaluated as an applicator for radio-frequency heating of biological materials. The operating efficiency of this applicator and the distribution of the electric field established within a simulated biological sample are determined for a number of modes of excitation. It is shown that uniform heating to a substantial depth is possible at efficiencies in excess of 80%.<
