Total <strong>in</strong>visibility by us<strong>in</strong>g geometrical transforms (theory)and metamaterials (theory and experiment)Pr<strong>in</strong>ciple: Surround the object desired to be <strong>in</strong>visible by a metamaterial speciallydesigned to distort the light ray paths through the metamaterial (red l<strong>in</strong>es below)by-pass<strong>in</strong>g the object, and then to restore them after the object exactly as theywere before by-pass<strong>in</strong>g the object (same positions and slopes) <strong>in</strong>visible objectSite Prof. Ulf Leonhard, St. Andrews Univ., UKhttp://www.standrews.ac.uk/~ulf/<strong>in</strong>visibility.htmlASTiGMAT
