  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 [J. Appl. Phys.
96, 1293 (2004)], 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.
