Abstract:

This is the final report on work performed at the Institute for Telecommunication Sciences on “Atmospheric Transfer and Shielding Properties in the 50 to 75 GHz Band” (ARO Proposal NR. 12233 GS).

The microwave spectrum of oxygen (02—MS ) was investigated with a pressure-scanning dual-resonator spectrometer between 53 and 64 GHz and with a nonresonant cavity spectrometer at 119 GHz under simulated atmospheric conditions. This summary is intended as a wrap-up and guide to the various outputs covering three main topics : new spectroscopic measurement technique; extensive O₂-MS laboratory studies; and engineering formulation and modeling of clear air (molecular) EHF radio path transfer properties.

Keywords: atmospheric propagation; oxygen microwave spectrum; dispersion spectroscopy; EHF transfer function
