Device for applying a programmable excitation electric field to a target

摘要

A device for applying a programmable excitation electric field to a target (P) comprises a plurality of elements (9; 10) for producing a plurality of single electric fields which are placed at predetermined locations into said target (P); the elements (9; 10) are formed by coils (9) and/or couples of electrodes (10) operatively connected to electric energy feeding equipments (8) and to a control unit (11) capable of adjusting the electric energy feeding to each of said elements (9; 10) for controlling the intensity of any single electric field and giving rise to a resultant excitation electric field which is the weighed sum of the single electric fields. <IMAGE>
