Terahertz Optical Constants of Air by Characteristic Matrix Method
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 2
Abstract
In this paper, terahertz optical constants of 12 % RH air are reported by using characteristic matrix method. In the terahertz time-domain spectroscopy experiment, the radiation was generated by optical rectification and detected by electro-optic sampling in ZnTe. The transmission of radiation through the five layered reference system nitrogen gas-teflon-nitrogen gas-quartz-nitrogen gas and sample system air-teflon-airquartz was modeled by characteristic matrix (CM) method. An error function involving the experimental transmission coefficient and transmission coefficient modeled by the CM method was minimized to extract the optical constants of air at 12% RH.
