I have some optical data from my Cr nanoarrays based on PAA membrane. These nanoarrays shows the normal behavior and normal shifts of longitudinal and transverse surface plasmon with s-polarized light but there is strange behavior with p-polarized light. I think this may be type of surface plasmon degeneracy but I could not confirm that. If any expert would like to discuss the data with me and have some idea about the analysis of the data I have no problem to publish the data together.
