Measurement of Radiated Electromagnetic field Intensity due to Micro gap discharge as low voltage ESD

The micro-gap discharge shows very fast transition duration of about 32 ps or less. Besides, breakdown field strength was examined to corroborate the very fast transition durations of about 32 ps. Also, a relationship between breakdown field strength and radiated electromagnetic field intensity was examined in experimental study. As a consequence of the experiment using the system, the breakdown field strength was very high of about 80 MV/m in low voltage discharging of below 350 V. And so, the average electromagnetic field intensity is proportion to the breakdown field strength in under the maximum electromagnetic field intensity. In addition, maximum radiated EM field intensity shows approximately 3.5 Vp-p respectively, the field radiation due to micro gap discharge has the some limit value in the maximum.
