英文摘要： The theory, design, preparation and applications of left-handed metamaterials (LHMs) were investigated in this project from the perspectives of eletromagnetic theory, physics and material science. The main achievements of this project can be concluded briefly as follows. (1) Mirror-symmetry design principles for magnetic and electric resonators were proposed. Generlized design methods and principles of LHMs based on magnetic and electric resonators were established. (2) The concept of multi-band LHMs was proposed and experimentally verified. Three-dimensional isotropic LHMs were designed based on coplanar elecric/magnetic resonant structures and Jerusalem corsses, respectively. (3) Dielectric resonators were introduced to LHM design. LHM design method based on all-dielectric ceramic resonators was proposed and many ceramic-based LHMs were designed and experimentally verified. (5) The constraint equation for the material paramters of left-/right-handed interfaces was obtained. Genreal theory of wave-shape control using metamaterials was established. Many novel functional devices including wave-shape controller were designed. (6) The concept of open cloak was proposed and the corresponding general design principles and methods of open cloak were also established. (7) Metamateial absorbers based on eletric/magnetic resonators, L-C resonant circuit were investigated. Frequency selective surface design idea based on metamaterial effective medium theory was proposed and verified.
