Study on Anisotropic Materials to Enhance the Efficiency of the Photon Absorption in Optical Devices

In this paper, a study of photonics on nano-scaled metal and nonmetal units consisting of layers of different atoms and molecules to form an optical device was presented. The optical strength can be maximized by adjusting material properties and the angle of incident light in the absorption layer, where the light resonantly excites surface plasmon polariton(SPP) in the SPP employed device. The purpose of this research is, through calculations and the use of a computer program, to find new combinations of metal and nonmetal units or metamaterials. The optimal incident angle of the light wave and the effective index were found with the use of Maxwell's equations and by modeling various metamaterials with multi-layers where efficient surface plasmon polariton was created. Their types of materials and size of layers showed propagating waves of light in an unconventional manner, such as Hyperbolic dispersion, which is anisotropic propagation.
