Abstract :
In this paper, the first direct mapping of the UV SPPs on an Al2O3/Al surface is studied. A near field scanning optical microscope (NSOM) system is set up for measurement in the UV domain. Numerical modeling results are also presented to analyze the distribution properties of the UV SPPs.
