摘要：

Specific localized surface plasmons which exist at rough thin metal films have been observed using near-field microscopy of second-harmonic generation. The second-harmonic field distribution over a pit on the film surface has been imaged and compared to model predictions. The technique of near-field microscopy of second-harmonic generation will be useful for investigations of localized electromagnetic excitations at disordered surfaces. (C) 1999 Elsevier Science B.V.
