Heating pattern of a single-loop applicator buried in muscle-equivalent phantom material measured at S-band.
We measured the initial rate of energy deposition at S-band (2.455 GHz) for a single-turn grounded insulated coil buried in muscle-equivalent phantom material. Most of the electromagnetic field is confined within the horizontal dimensions of the coil, and 30% or more of the incident energy is deposited at depths up to 1 cm below the coil. We believe that this device, sheathed in biocompatible PTFE teflon, could be implanted in a tumor region and left in situ during the course of a fractionated hyperthermia protocol.
