Equivalent current model for assessing human exposure to inhomogeneous LF magnetic fields

A novel equivalent current model is proposed for evaluation of the induced electric field inside the human body due to exposure to a low-frequency magnetic field. The reconstruction of the equivalent current source adopts radial basis functions, which requires measurement of only one single magnetic field component. The magnetic vector potentials inside the human body obtained from the equivalent current is then incorporated into numerical calculations of the induced electric field inside human body. The accuracy of the proposed model has been demonstrated by comparing the electric field inside a homogeneous human model to that of the full-wave simulation.
