Abstract | Conventional optical imaging systems cannot resolve the features smaller than approximately half the size of the working wavelength, called the diffraction limit. The superlens theory predicts that a flat lens made of an ideal material with negative permittivity and/or permeability is able to resolve features much smaller than working wavelength through the restoration of evanescent waves[l]. We experimentally demonstrated the superlens concept for the first time using a thin silver slab in a quasi-static regime; a 60nm half-pitch object was imaged with λ=365nm illumination wavelength, λ/6 resolution[3], and the imaging of 50nm half-pitch object under the same light source, λ/7, was also reported[4]. Here, we present mainly experimental studies of near-field optical superlens imaging. © 2006 Materials Research Society. |
