Effect of position of the pole coils to inductive regional heating

In this paper, the researches propose to study the effect of position of the pole coils to inductive regional heating. The focused is to determine the wide area which the heat is uniformly distributed. The result from this research was believed to be effectively applied to the cancer treatment. The design was pole coils which wear set of two pole coils, four pole coils, six pole coils and eight pole coils respectively. It was source operating at frequency of 2.45 GHz. The distance between lossy medium to pole coils was 3 mm., 5 mm. and 10 mm. respectively. The distributed of lossy medium was analyzing using finite difference time domain (FDTD). As the results of heating area simulation, many pole coils generated low heat, wide heating area and uniform distribution. However, less pole coil generated high heat and not uniform distribution. The pole coils was near lossy medium generated maximum heading, nevertheless it was not uniformly. Moreover, the pole coils was far lossy medium generate minimums heating, it was uniformly. The results from investigation can be applied and another advantage is its costs effectiveness.
