Study on the Astrophotonical Properties of Composite Dielectric Materials Using Computational and Theoretical Analysis

Cosmic rays were considered as lights passing through the nanomaterials to find relevant, effective indices using the dispersion relation. The objective of this research is to observe the photoelectric effect and the Surface Plasmon Polariton formed on the surface of metal particles on a nanoscale grid using cosmic rays that can be collected from space and also by visible lights. It is possible to manufacture or model nanocomposite materials such as silicon, beryllium, and germanium. Ultraviolet protons, part of cosmic radiation, are charged with very high energy. This proton has enough energy to cause the photoelectric effect by leaving the metal's electrons. Using the photoelectric effect as a composite of metal and metal oxide, and applying the Surface Plasmon Polariton effect to the nano double material, energy conservation ability for various materials can be measured. First, we investigate materials that can be used for nanoscale grid devices. After investigating possible combinations of metals and metal oxides, permittivity, refractive index, and light extinction coefficient, various metals and non-metals are used to find optimum incident angles.
