中文摘要： 空间波高效调制在通讯、电子对抗等领域具有重要应用前景。针对空间波调制，项目提出基于纵向耦合人工表面等离激元（LC-SSPP）的时间-空间色散调控进行空间波调制的思想。围绕这一思想，重点开展LC-SSPP的时间-空间色散调控机理和宽带高效LC-SSPP耦合媒质设计技术研究；在此基础上，开展LC-SSPP时间-空间色散特性设计理论与方法研究，以及基于LC-SSPP色散调控的消色差功能器件、新型天线罩等的设计研究。通过项目研究，阐明LC-SSPP时间-空间色散调控机理，解决空间波与LC-SSPP高效耦合转化的关键技术，设计出基于LC-SSPP色散调控的消色差平板透镜、高增益天线、宽带波束调控天线罩等，完成原理性验证实验，建立基于LC-SSPP色散调控的消色差器件设计理论和技术，为宽带消色差空间波调制提供理论支撑和技术途径。

英文摘要： High-efficiency modulations on properties of free-space EM waves possess wide important application values in communication, electronic countermeasures, etc. Aimed at high-efficiency free-space wave modulation, this project proposes to modulate the frequency-, time-, polarization-, space-domain properties of free-space waves based on spatial-temporal dispersion engineering of longigudinally coupled spoof surface plasmon polariton (LC-SSPP). This project will firstly carry on researches on the mechanisms of spatial-temporal dispersion engineering of LC-SSPP and the design of high-efficiency wideband LC-SSPP couplers. On this basis, this project will further carry out systematical investigations on the design methods of spatial-temporal dispersion properties of LC-SSPP. Then, LC-SSPP dispersion engineering will be applied to the design of achromatic functional devices, novel radomes, etc. Through these investigations, we will make out the mechanisms of spatial-temporal dispersion engineering of LC-SSPP and solve the key technical problem of designing high-efficiency LC-SSPP couplers. Many novel and high-performance devices will be designed and fabricated, such as achromatic planar focusing lens,high-gain antennas and broadband beam steering radomes. Proof-of-principle experiments will be carried out to verify the fundamentals. At the end, this project will finally establish the design theory and techniques of achromatic devices based on dispersion engineering of LC-SSPP, which will provide solid theoretical foundations and technical routes for high-efficiency achromatic free-space wave modulation.
