Simple analytical model to use in CAD tools for designing FSS devices: plasmonic transmission through hole arrays in thin films

Abstract Modeling of nano-structured plasmonic surfaces in optical range has attracted great attention recent research for its various properties such as filtering and enhanced transmission light. In this paper, we present a simple nanocircuit model that can be integrated CAD tools to design filters perfect absorbers FSS devices are based on through thin films structured by hole arrays. To illustrate the potential, applied it both circular square arrays silver film. The is demonstrated different structure parameters (hole size film thickness) frequencies. We show results compare numerical calculations obtained from COMSOL Multiphysics software with acceptable deviation achieves good matching previously reported experimental measurements.
