Shape effect of silver nanoparticles on plasmon properties of DLC: Ag nanocomposites

The optical constants of the diamond-like carbon films doped by silver nanoparticles were modeled using the Maxwell-Garnett approximations. Comparison between the extended and renormalized Maxwell-Garnett theory was conducted. Absorption cross-sections of spheroidal particles (prolate and oblate) in air and DLC film were calculated.
