Metal nanoparticles due to their unique electronic, optical and magnetic properties found a huge interest for researches. In particular, the nanoparticles of noble metals such as gold, silver and copper received a significant interest as plasmonic nanomaterials [1]. Lately, the optical elements created on the basis of the nanocomposites materials are subject of research. The peculiarity of the use of such materials is acquire fundamentally new properties that do not have existing materials with the decrease in the size of structural elements and their use are useful in a number of applied science and technology [2].
In this work the results of theoretical modeling of the optical absorption spectra of thin films of nanocomposite materials composed of copper nanoparticles embedded in a diamond-like carbon film. The optical characteristics of diamond-like carbon film with copper inclusions are considered within the framework of the effective medium approximation. The evolution of plasmon resonance characteristics and optical properties due to changes of dielectric constant of diamond-like carbon film and size, shape and concentration of the embedded metal nanoparticles is studied.
