The use of a solid immersion lens (SIL) is a promising technique for increasing areal density in optical disks. This lens produces a high numerical aperture beam yielding to tighter focus. Both near-field and propagating waves are important for the formation of the high aperture focus at the SIL-air interface. The conventional SIL system generates evanescent waves carrying the high frequency information of the focus, necessary to maintain the small size of the spot. Thus the recording media is maintained in the high-amplitude evanescent wave vicinity. By attaching a new imaging component to the lower surface of a conventional solid immersion lens it is possible to refocus the first spot with its subwavelength dimension and analyse the mean corresponding properties: the propagation of electromagnetic waves in nanostructured material and restoration of the near-field waves in the image plane. This new nanostructured component can image the focus of the optical pick-up at the lower surface of the SIL to the active layer of the disk. We use numerical simulation through finite-element method to show how this new imaging structure can restore the near-field waves many wavelengths away from this component and conserve/enhance the size of the focus. So we take the example of a finite 2D periodic structure of dielectric with a subwavelength lattice constant. The parameters of the super-lens structure allow imaging of the immerged focus by amplification of the near-field waves.
