The propagation of electromagnetic radiation from 500 to 4200 Mc in a coaxial cage transmission line passing through a cylindrical discharge chamber is investigated experimentally. Measurements are conducted in argon, helium, and nitrogen gas at pressures between 0.09 and 2 mm Hg for a discharge- electromagnetic radiation interaction length of 30.48 cm. The results are compared with theory, using a Lorentzian model to describe the electron motion in the presence of the r-f field. A graphical method for determining the plasma frequency and electron momentum transfer collission frequency from measurements of the power transmission coefficient at two different radio frequencies is discussed. A comparison is made between the plasma frequency determined by this method and that obtained by the use of a cylindrical Langmuir probe. The electron momentum transfer collision probability is calculated from the r-f and probe data. (auth)
