Patent ID: 7852282

Claim:
A module for receiving at least one electromagnetic wave moving along a path in a direction of propagation, the module comprising: a first substantially electrically conductive strip extending between a first end and a second end thereof disposed in a first pattern substantially in a first plane; a second substantially electrically conductive strip extending between a first end and a second end thereof disposed in a second pattern substantially in a second plane; the first and second strips being positioned substantially parallel to each other and spaced apart by a predetermined distance, and the first and second strips being electrically connected to each other; the first and second patterns being substantially opposite to each other, such that current passing through the first and second strips generates respective electromagnetic fields which are substantially opposed to each other; and the first strip being positionable in the path of said at least one electromagnetic wave and substantially transverse to said direction of propagation, for providing a protected region from which said at least one electromagnetic wave is substantially excluded, said protected region extending from the second strip and substantially away from the first strip.
