Description

<jats:title>ABSTRACT</jats:title><jats:p>It is shown that when transparent dielectric particles are deposited on metallic surfaces, excitation of surface plasma waves (SPW) becomes possible. The coupling of light with SPW is done via mirror-image effects. A drop in reflectance is observed at the resonance frequency in a similar fashion as in surface roughness experiments. Experimental evidence is proved by depositing very thin layers of hafnium oxide as well as tin oxide on silver surfaces.</jats:p>
