摘要：

We experimentally demonstrate a prototype of a cylindrical enlarging lens capable of enhancing and restoring evanescent fields. The enabling phenomenon is the resonant excitation of coupled surface modes in a system of two cylindrical arrays of small resonant particles. As was shown in [S.I. Maslovski, S.A. Tretyakov, P. Alitalo, J. Appl. Phys. 96 (2004) 1293], this phenomenon in planar arrays can be used in electromagnetic near-field imaging. Here, we use a similar structure in a cylindrically symmetric configuration, which gives us a possibility to obtain an enlarged near-field image. (c) 2006 Elsevier B.V. All rights reserved.
