Abstract : Dielectric properties of candidate materials for hypersonic vehicle radomes, which can reach above 1,500Celsius, are required. Although there has been recent study for temperature dependence of dielectric constants, little is known near or above 1,500Celsius. Current research uses laboratory-sized furnaces to achieve these temperatures, but this also requires large-sized and expensive samples. To reduce these costs, this thesis modeled a rectangular waveguide aperture-coupled to a 1.016cm-height, 1.1415cm-radius cylindrical cavity designed to operate at a resonant frequency of 10GHz. It utilized the electromagnetic cavity-perturbation method to optimize the research of small dielectric disk samples. The objective was to model a much smaller system, produce an empirical relationship between cavity resonance and the samples dielectric constant, and create a prototype of the design to validate this concept.
