| Summary: | 碩士 === 國立成功大學 === 電機工程學系 === 103 === There are two main subjects in this thesis. First, we will discuss the low loss corundum-sructured A4B2O9 dielectric ceramic material, and make a thorough inquiry to the influence of different kinds of doped ions in order to improve its microwave dielectric properties and applications. Second, there will be an emphasis on the prediction of the maximum quality factor of four kinds of doped materials in the fully-densed condition, and the relation between the loss tangent and porosity in different doped ions and temperature.
