Patent ID: 8860627

Claim:
A reconfigurable reflector for radio-frequency waves, comprising: a rigid support element having a front surface, the front surface being rigid; an elastically deformable reflective membrane adapted for reflecting radio-frequency waves and microwaves and lying on the rigid front surface of said rigid support element; and a plurality of linear actuators for deforming said reflective membrane by operating on predetermined points thereof; wherein said linear actuators are embedded within said rigid support element, and have shafts protruding from the rigid front surface thereof for operating on predetermined points of said elastically deformable reflective membrane with strokes ranging from 0 mm to 20 mm; said deformable reflective membrane has a sufficient thickness to accommodate strokes from linear actuators up to 20 mm, wherein said rigid front surface is not deformed when said reflective membrane is deformed by said linear actuators, and further wherein said elastically deformable reflective membrane, in an undeformed state thereof, contacts the rigid front surface of said rigid support element and matches its shape.
