Perfect cylindrical lenses

JB Pendry

Abstract:

A slab of negatively refracting material is known to focus light and if the focussing will be perfect, producing an image which is an exact replica of the object. Magnifying the image requires a new design concept in which the surface of the negatively refracting lens is curved. Here we show how a hollow cylinder of material can be designed to magnify an image but otherwise with the same perfection as the original lens. Curvature requires that and are now a function of position.
