Starting from the measurement of the electric field around the phantom, the field prediction is obtained by solving a boundary value problem. This allows to avoid the description of the electromagnetic source and the estimation of the electric field distribution also when the illuminating source is unknown or when its numerical model is not available. In order to show the effectiveness of the proposed approach, some numerical results, concerning a two dimensional geometry, are provided. Firstly, the accuracy and validity of the electromagnetic prediction are assessed by comparing numerical with reference solutions (analytically computed). Then, in order to demonstrate the efficiency, the robustness and capability of this technique, different measurement strategies, noisy environments and errors in the data acquisition are taken into account.
