When electromagnetic waves propagate through metamaterials they display properties different from those found in natural materials. These different properties can include negative refraction (light is bent in the opposite direction from that expected from general laws of physics), flat lens focusing, and subwavelength imaging. The use of meta-materials to direct electromagnetic beams is a highly promising approach to overcome current limitations of conformal antennas by improving the radiation characteristics of antenna elements, especially those at the edge of phased array antennas. 收起
