AN ERROR BASED APPROACH TO THE SOLUTION OF FULL MAXWELL EQUATIONS

Aim of this paper is to extend the error based approach to the study o f general electromagnetic problems in 3D geometries in which the displ acement currents may not be neglected. The unknown variables are the, three-component vector potential A and W defined as the time integrals of -E and H, respectively. These potentials are constrained to satisf y initial, boundary and interface conditions. Since in this way the Ma xwell equations are automatically satisfied, the solution is obtained via minimization of a global error functional which approaches zero wh en the constitutive equations are satisfied.
