Abstract
"Radiation patterns resulting from an array of waveguide-fed apertures, filled with assymmetrically [sic] cut dielectric inserts, in an infinite ground plane were investigated. The results of Blumberg and Hemmen concerning single apertures were applied to a two-aperture array, with emphasis upon obtaining an array capable of scanning in the far field through changes in the permittivity of the assymmetrically [sic] cut dielectric inserts. Scanning was shown to be possible with up to a 60⁰ scan angle with a "push-pull" method of varying permittivities, in which the permittivity of one insert is raised while the other is lowered. The aperture field data obtained by Hemmen was improved upon, and the results used, with the aid of a computer, to predict far field patterns. In addition, standing waves present in a nanechoic chamber constructed by Blumberg were removed and improved performance characteristics of the chamber resulted"--Abstract, page ii.
