In all the simulations, the permittivity of the silver is described by the Drude model, ε (ω) = ε - ωp2 [ω (ω-i Vc)], where the high-frequency bulk permittivity ε =4.2 the bulk plasmon frequency ωp =1.346× 1016 rads, and the electron collision frequency Vc =9.617× 1013 rads., the result fits the permittvity of silver in near-infrared range from Handbook of Optical Constants of Solids, edited by, E. D. Palik, (Academic, Boston, 1985).
