Abstract
In this work we show that the chromatic aberrations inherent to optical glass lenses may be eliminated for all the wavelengths of the visible spectrum by coating a standard glass lens with a nanowire spatially dispersive metamaterial characterized by anomalous frequency dispersion. A finite-difference frequency-domain (FDFD) based method is proposed to solve the Maxwell-Equations in the presence of spatially dispersive bodies.
