Patent ID: 7907101

Claim:
A configurable bipolarization reflector comprising: first and second intersecting sets of parallel composite lines (LH i , LV j ), a line segment between two consecutive intersection points (I ij ) of the first and second intersecting sets of parallel composite lines containing a switchable conductivity component ( 12 ) having conductivity that can be switched by a switching signal (V), wherein the switchable conductivity components disposed on the segments along the lines (LH i ) of the first set present an alternating conductivity direction, and the switchable conductivity components disposed on the segments along the lines (LV j ) of the second set present the same conductivity direction; and means for applying a switching signal (V) in order to switch the conductivity of the components of a group of segments defining a reflector area (Z) of given reflectivity, wherein the switching signal (V) is applied between: firstly, a first point (P 1k ) of intersection of said first and second intersecting sets of parallel composite lines situated on a first outermost line (LH 1 ) of said first set and a line (LV k ) of the second set, the switchable conductivity components ( 12 ) of the segments adjoining said intersection point (P 1k ) being conductive in response to the switching signal (V); and secondly, two second points (P k−1,N , P k+1,N ) of intersection of said first and second intersecting sets of parallel composite lines situated on a second outermost line (LH N ) of said first set, on the side opposite the first line (LH 1 ), and on two lines (LV k−1 , LV k+1 ) adjoining the line (LV k ) of application of the first point (P 1k ) of intersection.
