ABSTRACT:
A wave action device for beams of radio frequency waves operates as an electromagnetic lens at an electromagnetic wave relay station to redirect the electromagnetic beam in selective high concentration of the beam to one or more specific points. The device is positioned in the region of an electromagnetic wave link and intercepts the electromagnetic beam, barring that portion of the beam which forces the appearance of a null field at selected points of reception. The phase and the amplitude of the remaining portion of the intercepted electromagnetic beam are modified to redirect the remaining portion of the beam in a passive manner. The remaining portion of the beam is selectively concentrated and diverged with respect to the selected points of reception.
