| Zusammenfassung: | An apparatus and method is described for generating an electromagnetic, or acoustic field by use of a number of field sources in order to produce a field anomaly at a known target location. The field anomaly is characterized by having a wavefront at the target location that has a predetermined desired orientation so that at the target location the field appears to emanate from a different direction to that perceived at field locations away from the target. |
