The results of a one year theoretical and experimental investigation of the properties of a cylindrical plasma column used as a scanning microwave antenna are presented. A complete mathematical treatment is given for a new class of fast wave modes for an open, cold plasma column in the absence of applied magnetic fields. Experimental results presented include antenna patterns, impedance measurements, and noise measurements. The results for different plasma operating parameters and microwave feed configurations are reported. Good agreement is obtained between experimental behavior of the antenna and the properties of the fast wave modes. Most serious experimental problem is the production of homogeneous plasmas. Authror
