Abstract :
Electromagnetic and heat-transfer equations were solved to investigate a radio frequency (RF) rectangular resonant cavity applicator. The possibility of heating a deep-seated tumor was demonstrated. A torso-shaped dielectric phantom was made. It has electrical constants resembling those of human muscle. Several L-type antennas were made and placed at appropriate locations to heat a deep region. Measured results agreed with the calculated results. Results show that the rectangular resonant cavity applicator with the L-type antennas can heat deep-seated tumors
