Abstract :
The evaluation of eddy currents induced inside the human body by pulsed electromagnetic sources involves the characterization of tissues conductivity and permittivity values at different frequencies. The transient problem requires the transformation of the dispersion relation into a time domain relation by a convolution integral. Comparisons of results using different material properties for a pulsed excitation due to a resistance spot welding system are presented.
