Abstract: Research on high frequency magnetic properties put forward higher demand for the excitation device. For accurate measurement of magnetic material magnetic properties, a test method for magnetic properties of two dimensional was proposed, a new excitation device and sensing structure were used, and the shielding structure designed for the two dimensional magnetic excitation device was conducted whose shielding effectiveness could reach 61.699dB. The influence of DC magnetic bias and power frequency clutter and low frequency clutter on the experimental in the test process was discussed, and the solution was proposed. The experimental results show that the proposed method is practical and effective and feasible.
