MEASUREMENT OF ELECTRICAL PROPERTIES OF HIGH TEMPERATURE RADOME MATERIALS BY MEANS OF THE XB 3000A DIELECTROMETER.
Abstract
The XB 3000A dielectrometer is an instrument used to measure the dielectric constant and loss tangent of radome materials up to a temperature of 3000F. In the report a set of operational procedures and techniques necessary to achieve measurements which are comparable with published data is described. The theory and mathematical development of the method of determining the dielectric constant and loss tangent from preise measurements is shown. Sources of errors and their affect on the overall instrument accuracy are discussed. Extensive tests were carried out on the determination of the dielectric constant and loss tangent for several materials at elevated temperatures. The accuracy to which the dielectric constant and loss tangent may be obtained is determined by means of comparing data realized with standard published data for a sample of Corning 9606. Results indicate that the dielectric constant can be determined to a nominal limiting error of 1.0% and loss tangent to a nominal accuracy of 0.0008. (Author)
