要約(英語): Transient characteristics and frequency spectra of impulsive electromagnetic radiation caused by ESDs were examined experimentally in order to clarify an EM radiation mechanism. The experimental system consists of a pair of spherical electrodes, a 1-18 GHz band width horn antenna and a 20 GHz bandwidth digitizing oscilloscope. Discharge voltage is less than 600 V in this experiment. As a result, the waveform duration and first peaks of the EM field radiation can be explained from a dipole antenna structure which makes a pair of spherical electrodes. Furthermore, as the excitation factors of the EM radiation from electrode elements are mentioned the current path length of the electrodes, and transient speed di/dt of discharge current. In addition, the frequency spectrum distribution of the received voltage was found to be related to the excitation path length determined by the size of the spherical electrode.
