Superfocusing of a surface polariton in a wedge-like structure. Nerkararyan, K. Physics Letters A, 237(1–2):103--105, December, 1997. Paper doi abstract bibtex 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.
