  • Abstract
    An empirical investigation of metallic diaphragms deformed by uniform normal pressure to produce accurate parabolic reflectors is discussed. 30-cm diameter ( f/D =0.4 ) reflectors produced by this technique were measured mechanically and found to have maximum deviations of only 0.5 mm or \\lambda /20 at 30 GHz from a true paraboloid within a circle of 14-cm radius. Electrical measurements at 30 GHz are discussed.
