Theoretical and experimental study of the electromagnetic field generated by ESD

摘要

In the paper, electromagnetic field radiated by a thin wire with ESD current injected is studied theoretically and experimentally. A numerical model of the field distribution is established using FDTD method and characteristics of the radiation field are analyzed after calculating. The results show that the radiation field generated by the thin wire with ESD current injected is a kind of oscillation field and is far stronger than that generated by ESD spark at the same condition and the calculation results obtained by FDTD method are in agreement with the experimental results.
