Abstract
Examples of the present invention include methods and apparatus for modification of electromagnetic waves, including lenses with generally parallel flat surfaces. Lenses may comprise metamaterials, dielectric materials (such as glass), plastics, and the like. Lenses may have an index profile corresponding to a coordinate transformation for the desired effect on the electromagnetic waves.
