Popis: A study of the effect of electrostatic discharge (ESD) to a coaxial cable which connects two systems was made. To study the effect of various pathways of ESD, we used a finite-difference time-domain (FDTD) algorithm. The disturbance induced in the inside of the cable is evaluated by using the transfer impedance of the cable shield. The effect of ESD on the cable shield is studied as well as the effect of the cable's presence when a remote part of the connected system is targeted. The results of our study show that the effect of ESD entering the cable shield can potentially be a lot more dangerous than the signal entering through a typical aperture, especially if the frequency content of the discharge is high. A cable also provides a good conductor for ESD signals to reach other parts of the system.
