Abstract

Impulsive electromagnetic waves are produced when a grounded human touches a conducting object with different potential. An experimental setup was designed to measure electromagnetic fields on humans caused by sparks. The measured and computed waveforms are in good agreement. Specifically, measured and computed rise times of a discharge current were approximately 100 ps for a charge voltage of 1 kV. The generated electromagnetic pulses were distorted and dissipated with propagation due to dispersive characteristics of the biological tissues and multireflection in the human body. Computational results suggest that the pulse propagates over the body and is emitted from the top of the head in 10 ns.
