Paper Title:

Advanced Dielectric Materials for Space Exploration

Abstract:

Future attempts in space exploration and the harnessing of energy from the sun for transmission back to earth would require the use of materials that possess good dielectric properties and capable of withstanding extensive thermal cycles. This investigation focused on the development and identification of materials with suitable dielectric properties in the microwave frequency range (397MHz – 2.45 GHz) for the design and development of thermo-electric systems, which can be used to generate electricity in space stations and satellites. This required extensive characterization of dielectric properties of potential materials including POCO Graphite AXZ-5Q, manganese oxide, boron nitride, other materials or combinations of materials. The system used for the dielectric characterization was based on the cavity perturbation technique, which measured the complex scalar permittivity of materials at six resonant microwave frequencies and temperatures up to 1400° C.
