Abstract

This research was conducted to visualize the frequency-dependent electromagnetic field distribution for electromagnetic compatibility (EMC) applications and the time evolution of the current flow induced by an electrostatic discharge (ESD) on complex-shaped electronic systems. These objectives were achieved by combining magnetic field probing with a system that automatically records the probe's position and orientation. The local magnetic field associated with the probe location was recorded and displayed at near real time on the captured 3-D geometry. Consequently, a field strength map was obtained for EMC applications. Also, a video showing the spreading of the ESD-induced current with subnanosecond resolution was captured for ESD applications after the ESD-induced surface current density associated with the probe location was recorded.
