Near-fleld intensity correlations insemicontinuous metal films

Spatial intensity correlation functions ofsemicontinuous metal-dielectric films of varying metal concentration, p,wereobtained fromnear-field microscopy. Thedata shows a transition frompropagation tolocalization andbacktopropagation ofoptical excitations with increase inp. 02005Optical Society ofAmerica OCIScodes: (180.5810) Scanning microscopy; (240.6680) Surface plasmons; (240.6690) Surface waves; (240.5420) Polaritons; (240.0310) Thinfilms; (160.3900) Metals
