Wave action device for radio frequencies
First Claim
1. A wave action device for a wave beam emitted from a source, said wave action device operating as a lens at a relay station remote from said source of said beam to redirect the beam in selective high concentration of said beam to one or more specific points, said wave action device being positioned in the region of a wave link at the remote relay station, said wave action device comprisinga pair of spaced supports;
- intercepting means for intercepting the beam to eliminate that portion of said beam which forces the appearance of a null field at selected points of reception, said intercepting means comprising elongated spaced blades of predetermined dimensions positioned in a plane substantially transverse to the direction of propagation of said beam, said blades having spaces of predetermined dimensions between them, each of said blades having a side knife-edge, spaced opposite ends and a longitudinal axis extending therebetween, each of said blades having a width of a dimension determined by the operating characteristics of said device, said spaces having dimensions determined by the operating characteristics of said device;
modifying means for modifying the phase and the amplitude of the remaining portion of the intercepted beam to redirect said remaining portion of said beam in a passive manner, said modifying means selectively concentrating and diverging said remaining portion of said beam with respect to said selected points of reception, said modifying means comprising said spaces and said knife-edges of said blades for modifying the phase and the amplitude of said remaining portion of said beam; and
mounting means mounting said blades at their ends on said supports in a manner whereby said blades are adjustably inclinable relative to horizontal.

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.
