Abstract
Computation of low frequency induced electric fields in the human body requires the knowledge of the source field. The source field can be reconstructed by measuring the magnetic field over a regular grid, or by identifying a model, among which multipoles. Spherical multipoles are easy to compute, but cannot be used close to the source. In this work it is proposed to use a new multipolar model which holds outside an arbitrary geometry – not limited to a sphere.File in questo prodotto:
