Plasmon polarized spectra of electrochemical gold surfaces modified by femtosecond laser radiation

This paper presents the process of creating a gold surface modified by periodic structures deposited by femtosecond laser radiation by two different geometry. The refraction processes of s- and p-polarized light on the gold structured surfaces with the changes in the dielectric permittivity function were studied and compared in this paper. The presence of surface plasmon generation on the rough gold surface in visible region at two frequencies has been established in this work.
