Abstract: Abstract: - In this paper, the design of applicator system for regional induction heating at 2.45 GHz and using noninvasive method. The distribution of the lossy medium was analyzed using the finite difference time domain method(FDTD). The objective is to determine the area which the heat is uniformly distributed. The result from this paper was believed to be effectively when it was applied to the cancer treatment. The applicator utilized was the inducting spiral coils which were sets of two coils and four coils, and each coil has its own power-supply unit. It was fabricated by using magnetron sources operating at frequency of 2.45 GHz. The energy supplied to the induction coil was timely controlled. The results from the simulation and experimental of heating area from lossy medium were compared. Both simulation and experimental results showed good no conflict. The activation of supply units one at a time generated more heating wide area than the one when all units!
were activated at the same time. The results showed that the applicator with four coils generates more heating wide area than the one with two coils. Another interesting point is that the activation each power supply unit was turned on one by one generates more heating wide area than the activation all power supply units were turned on. In this study, both two coils and four coils were capable of producing a temperature rise of 7 Celsius degrees for 10 min. Moreover, the results from this investigation can be applied to various designs of heating wide area applicator and another advantage is its cost effectiveness.
