Designing devices for sub-wavelength imaging using a transformation-optics approachVol 1 No 2 (2008)
Abstract: Two transformation-optics inspired flat lenses are used to build up an optical
system capable to transpose an area surrounding the object focal point in a magnified area
surrounding the image focal point. The object and image focal points of the system are placed in the
free space and respectively a dilated space having a sub-unitary relative permittivity and
permeability. The anisotropic and inhomogeneous media constituting the lenses enable the
processing of the high spatial frequencies waves without converting them in evanescent waves.
Numerical simulations show the capability of the proposed device to perform magnified discernible
images of the sub-wavelength details.
