Abstract:
The paper reports a new type of plasmonic metamaterial based comb filter with the metasurface as similar to the Salusbury window, and comprised of three layers – subwavelength sized periodic gold nanorods surrounded by freespace (i.e. the metasurface), silicon and silver nanolayers. The structure yields multiple absorption peaks upon impinged by electromagnetic waves. The metasurface behaves as comb filter – certain spectral frequencies are absorbed and the remaining ones are reflected back. The performance of filter is analyzed in UV, visible and NIR regimes taking into account the p- and the spolarized excitations under different angles of incidence.
