A Comparative Study on the Induced Current Density in Humans Exposed to ELF Electric Fields

A comparison between two theoretical methods, recently adopted for evaluating induced currents in a human body, is here presented. In both cases, a vertical ELF electric field is assumed for the coupling to a standard human subject. Specifically, the diakoptic method (DM), applied to a homogeneous multi-sphere model of man with low partitioning degree, and the Boundary Element Method (BEM), applied to a non-homogeneous model with high partitioning degree, have been selected. The analytical and numerical formulations, respectively distinctive of the above methods, are carefully described and a number of data are reported and commented upon.
