Single silver nanorod (the size is much less than the optical wavelength) is an excellent surface plasmon generator. Under the interaction with a polarized optical wave, the silver nanorod behaves like a funnel of the electromagnetic field, the gathered electromagnetic fields (surface plasmons) surround the nanorod. Due to the effect of the localization, the surface plasmons are highly enhanced in comparison with the incident wave. Consider a hexagonal nanocrystal which is constructed by identical silver nanorods, and the nanorods are embedded in a silica block. As a polarized optical wave illuminates on the crystal, a nanoimage is formed by the coupling of surface plasmons below the crystal. Interestingly, the nanoimage is dependent on the direction of the polarization, that is, the nanoimages are varied with the rotation of the polarization. On the other point of view, the nanocrystal is like a nano-kaleidoscope. The intensity of the nanoimage is higher than the incident wave, if the patterns of the nanoimages can be controlled, the applications of the nanoimages will never to be overlooked.
