A COMPLETE LINEAR DISCRETIZATION FOR CALCULATING THE MAGNETIC-FIELD USING THE BOUNDARY-ELEMENT METHOD

An analytic solution is derived for the magnetic field generated by cu rrent sources located in a piecewise homogeneous volume conductor. A l inear discretization approach is used, whereby the surface potential i s assumed to be a piecewise linear function over each tessellated surf ace defining the regions of differing conductivity. The magnetic field is shown to be a linear combination of vector functions which are str ictly dependent on the geometry of the problem, the surface tesselatio n, and the observation point.
