Abstract :
A formulation for the solution of the 3D eddy current problem is presented with the edge element method. The method can minimize the computation time of 3D nodal-finite element method in terms of potential and eliminate spurious modes resulting from solving magnetic field directly. Theoretical analysis and numerical modeling of saline-filled tank system demonstrate the accuracy of this method. The powerful method can be considered an important step towards the inverse problem of MIT and used to research on the spatial resolution, choice of the best operation frequency and the reconstruction of conductivity imaging of MIT
