摘要：

It is shown that during the propagation of a surface polariton through a system of two touching metallic semicylinders its wavelength decreases to zero as it approaches the edge of the groove. As a result, the polariton is focused in a very small region and the strengths of the wave fields increase anomalously. (C) 2000 Elsevier Science B.V. All rights reserved.
