Model of human body for electrostatic discharge analysis based on method of moments and frequency-dependent surface resistance

摘要

We present a model of human body for full-wave numerical analysis of contact electrostatic discharge. The model is based on frequency-dependent surface resistance distributed over the surface of the body, which models the measured parameters of human tissue. The numerical analysis is done by method of moments with surface integral-equation formulation in the frequency domain. The results for currents and fields in time domain are obtained using discrete (inverse) Fourier transform and frequency-domain data. The flexibility of the proposed model is tested and discussed by comparing the numerical results to the standard waveform of current in electrostatic discharge. The results for magnetic field, in the vicinity of the discharge, are compared to those found in the literature. The model predicts correctly both waveforms and peak values for currents and magnetic fields.
