Abstract

Chemical engineering of metamaterials to reduce optical losses is studied by first principle density functional theory. Contribution of the surface states to optical losses is studied by calculations of the imaginary part of the dielectric function for several organic molecules (water, methanol, and ethanol) adsorbed on the (111) surface of Ag nano-slabs. Substantial modifications of optical functions of metallic nano-slabs in near infrared and visible spectral regions, caused by surface states and molecular adsorption, are predicted, discussed, and compared to experimental data.
