Subwavelength imaging with nonmagnetic anisotropic bilayers.

A nonmagnetic compensating bilayer imaging system having two uniaxially anisotropic layers is described. Evanescent fields in vacuum are converted to propagating waves in the bilayer, and one layer compensates the phase progression of the other. In this way, subwavelength imaging performance is possible with substantial flexibility in operating wavelength. Conditions for enhanced resolution and sensitivity to the material parameters are examined with a view to fabrication.
