摘要：

It is shown that during the propagation of a surface polariton through a slender wedge its wavelength infinitely decreases as it approaches the edge of that structure. As a result, the polariton focuses in a very small region and the strength of the electric field increases anomalously. (C) 1997 Elsevier Science B.V.
