英文摘要: Dealing with the compelling application requirements for novel high-performance planar antennas in fields of military, aviation, communication, etc, we propose the academic idea of designing planar antennas based on unique electromagnetic properties of microwave surface plasmon polaritons by means of metasurfaces. To this end, the design, realization and applications of novel planar antennas based on the excitation and control of microwave surface plasmon polaritons will be explored profoundly. The physical mechanism and operating principles of surface plasmon polariton planar antennas will be illustrated. The design theory and design methods of microwave plasmon polariton planar antennas will be established as well. The influence rules of gradient metasurfaces on the mode selection, high-efficient excitation, low-loss transmission and controllable radiation will be investigated. The design theory and design methods of the feeding structures of surface plasmon polariton planar antennas will be also established. Furthermore, according to practical application demands, we are going to carry out design and experiment investigations on surface plasmon polariton planar antennas with technical performances of low-profile, high directivity, frequency sweep, stealth, etc. Through the above work, the design theory, realization methods and technical application schemes will be established finally. The research work of this project will provide solid theoretical background and brand-new technical means for developing novel high-performance antenna systems.
