Generalized Electrical Image Method for Field Reconstruction

A technique for magnetic field reconstruction is proposed with the use of a generalized electrical image method (GEIM). The basic idea behind the GEIM is that by understanding fundamental properties of the strategic dual image (SDI) method and applying the equivalence principle on the SDI boundary, a simple form of the interior/exterior magnetic field can be determined. As an example of this technique, a field reconstruction of a quadruple magnet is demonstrated.
