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.
