Study on Optical Behaviors of Materials for Galactic Cosmic Radiations

Recently, the research on Galactic Cosmic Rays (GCR) has been accelerating with the progress of space development, such as Moon-Mars exploration.

The energy of radiation from GCRs and solar energetic particles (SEPs) is recognized as very high.

Especially, the GCRs are active and high-energy particles that rained down on the earth from our galaxy and extra-terrestrial galaxies. To capture and utilize GCR energy, Surface Plasmon Polariton (SPP) is considered to be quantum nanotechnology that can control the formation of surface electromagnetic waves by absorbing optimally incident energy into the nanoscale composite system. The objective of this research is to further explore whether the SPP phenomenon occurs by capturing the light energy of various wavelengths into the nanoscale composite structure. 

 The type of wavelength and combination of various nanomaterials are used as important variables. The refractive index, extinction coefficient, and relative permittivity of nanocomposite materials are used as input data for simulation. 

In addition, to understand how the electromagnetic distribution changes when these materials are exposed to GCR in outer space, the optical behaviors of the system were observed while various physical conditions are changing.
