Calculation of strength of electrical and magnetic fields at a distances commesurate with a length chanel of electrostatic discharge

Electrostatic discharge is source of dangerous radiated electromagnetic interferences for semiconductor devices of printed circuit boards. Electric field radiated by electrostatic discharge at the distances commensurate with the length of the discharge channel reaches the high values and may lead to induction of currents and voltages which may lead damage of semiconductor devices and integrated circuits. The paper presents results of calculation of strength of electric field at a distance commensurate with a length channel of electrostatic discharge. The paper presents time domain diagram of strength of electric field when electrostatic discharge is occurred on printed circuit board.
