How High is the Level of Electromagnetic Fields Radiated by an ESD?

Quantitative estimation of the electromagnetic fields radiated by electrostatic discharges (ESD) is of importance to the users and computer industry. Analytical and experimental results, based on a new theoretical model and specific measurement system, are presented to achieve this objective. The ESD spark is modeled as an electrically short, time dependent, linear dipole situated above an infinite ground plane. The specific measurement system consists of a newly designed broadband, time-domain TEM horn antenna, a wideband digitizing oscilloscope, and a desktop computer.
