Fields radiated by electrostatic discharges

The problem of electrostatic discharge (ESD) radiated fields problem is examined, both theoretically and experimentally. Measurements indicate that the electric fields can be quite significant (>150 V/m at a distance of 1.5 m), particularly for relatively low-voltage sparks (<6 kV). A theoretical dipole model for the ESD spark is developed to compute the radiated fields. The agreement between theory and experiment is good. The model can be used to predict the fields for a wide range of possible discharge configurations.<
