Electromagnetic field mapping is accelerated by acquiring data from the surface bounding a volume of interest and solving the boundary value problem (BVP) using Green's function. Instead of measuring electromagnetic field components on a step-by-step basis at each point within a region of interest, only a component of the field, preferably the normal component, is measured on the surface bounding ...
