新型人工电磁表面功能器件

The research and application of metasurfaces is a frontier and hotspot in the field of artificial materials, and inhomogeneous, conformal and active metasurfaces will be the future focuses according to the developing trends. The project aims to explore the methods of characterizing, analyzing and applying the three kinds of metasurfaces, then establishes a complete process from theoretical analyses and software optimizations to the final functional tests. As a result, the project paves the ways for designing functional devices in actual application scenes. Based on the foundation, the project will design, fabricate and test a series of functional devices based on metasurfaces, including low-profile omnidirectional horizontal-polarized antenna, omnidirectional vertical-polarized antenna, integrated antenna and radome, near-field surface-wave lens and reconfigurable low-profile leaky-wave antennas. These devices are expected to be applied in the fields of radio frequency identifications (RFID), multi-input and multi-output (MIMO) antennas and radar communications.

新型人工电磁表面的研究与应用是当前人工媒质领域的前沿热点，根据其发展趋势，非均匀、共形和有源人工电磁表面将是未来研究的重点，本项目围绕这三种人工电磁表面制定了详细的研究方案。项目将首先研究非均匀、共形和有源新型人工表面的表征、分析及应用方法，建立从理论分析、软件优化设计到功能测试的完整流程，为针对应用场景设计实用型功能器件奠定良好的基础。在此基础上，本项目将设计、制作并测试一系列基于新型人工电磁表面的功能器件，包括低剖面全向水平极化天线、全向垂直极化天线、一体化天线-天线罩、表面波近场透镜和可重构低剖面漏波天线，这些器件可望应用于射频标签、多输入多输出通信天线系统和雷达通信等领域。
