We have simulated the Chalcogenide glass (ChG)-based nanostructures which are used as substrates for surface-enhanced Raman scattering (SERS). A discrete dipole approximation method was used and calculated results are compared to those of experimental. The results of simulation agreed well with the experiment. Furthermore, we have obtained conditions under which higher enhancement factors (almost by an order of magnitude) could be achieved by changing the polarization state and the incident angle of the beam on the surface.
