Fig. 4From: Scattering of partially coherent surface plasmon polariton fields by metallic nanostripe(Color online) Degree of spatial coherence |γ(0,x,0)| associated with the total SPP field on the metal surface with a d=4 μm, and b d=10 μm. The spectral intensity ratios are taken from Table 2. The dashed curve corresponds to the degree of spatial coherence in the absence of the nanostripeBack to article page
