초록

Due to high permeability of the ferrite core, the characteristics of the ICP are expected to be greatly improved. We investigated the effect of the ferrite cores on conventional inductively coupled plasma. It was observed that the current and voltage in ike ICP antenna are slightly decreased and the power transfer efficiency is increased. However, due to eddy current and hysterisis loss, plasma density in the ICP with the ferrite cores is not increased. It seems that the ICP with the ferrite cores at low frequency (${\~}$100kHz) will be greatly improved since the losses at the low frequency can be negligible.
