The quasioptical terahertz molecular spectra generator of atmospheric gases radiation

An important research topic is the spectral-molecular interaction between atmosphere gases and bio-environments. For this purpose, it is necessary to know the radiation spectrum structure of atmospheric gases over the terahertz frequency range (100 GHz to 10 THz). A quasioptical programmable EHF (extremely high-frequency) generator that operates over the terahertz frequency range of the molecular spectra of atmospheric air gases has been developed. Besides applications in the research of interactions between THz-waves and biological environments, the developed generator can be used for developing various radar and communication systems, for studying the propagation laws of THz-waves of various types, as well as the polarization and structures of spectra of the Earth's atmosphere, and for determining absorption bands and "windows of transparency" caused by the presence of various gases in the atmosphere and other environments.
