UNIFIED APPROACH TO ELECTROMAGNETIC SHAPE-INVERSE AND MECHANICALLY COUPLED PROBLEMS VIA A LAGRANGIAN TECHNIQUE

The aim of this paper is to present a Lagrangian unified approach to s hape dependent electromagnetic problems (equilibrium. dynamic coupled, shape inverse, trajectory inverse problems). The main features of thi s approach are illustrated, and a comparison with the usual Eulerian p oint of view is made, from both the analytical and the numerical side, showing several advantages of the Lagrangian approach, A simple analy tical example is presented in order to help comprehension and to show the effectiveness of the method, In addition, some practical applicati ons are described.
