摘要

Traditional electromagnetic (EM) measurement can't identify the electromagnetic interference (EMI) noise mechanism. In the paper, a novel method is proposed to analysis the radiated EMI noise sources by modern signal process. Then, the near Geld wave impedance approach is present to diagnosis the mechanism of radiated EMI noise. The results show that the suggested method is more valid, effective and convenient.
