Analysis of the human body exposed to transient electromagnetic fields is presented in this work. The human body is represented by one or more vertical conductors. Modeling of the vertical conductors is based on the transmission line (TL) theory in the frequency domain. The related transient response is computed using the inverse Fourier transform (IFT). Per-unit-length parameters are calculated for finite heights and the physical characteristics of the human and soil are taken into account. The assessment of the space–time dependent current distribution induced in the body is carried out in the general case where the human is not directly in contact with the ground. The results, related to various transient exposures, obtained with TL body representation are compared to the direct time domain results computed using the human equivalent antenna model of the body.
