英文摘要: On the basis of analyzing properties of all-dielectric metamaterials, all-dielectric metamaterials are introduced as the core component into the design of frequency selective surfaces, so as to meet the urgent need for isotropic, low-loss frequency selective surfaces that are suitable for high-frequency/high-power applications and can be tolerant of extreme environments. Firstly, based on optimal design of all-dielectric metamaterials, the filtering mechanism and performance improment will be carried out for all-dielectric metamaterial frequency selective surfaces. General design principles for all-dielectric metamaterial frequency selective surfaces will be established. Then, metamaterial effective medium theory will be introduced to guide the design of all-dielectric frequency selective surfaces. On this basis, in-depth investigations into application design of all-dielectric frequency selective surfaces will be carried out. Finally, the fabrication and performane optimizaton of all-dielectric metamaterial frequency selective surfaces will be investigated. Through the work of this project, the electromagntic filtering mechanism of all-dielectric metamaterial frequency selective surfaces will be elaborated. General design theory and application design methods of all-dielectric metamaterial frequency selective s
