【摘要】 本文提出由分裂谐振环(SRR)与电谐振结构(ELC)组成的一种功能可重构人工电磁材料通用单元。该结构使用两个理想开关来有效控制其电谐振和磁谐振行为,可灵活实现双正媒质(DPM)、电单负媒质(ENM)、磁单负媒质(MNM)、双负媒质(DNM)等四象限中不同的材料功能和相互转换。通过优化设计,功能可重构特性在同一频段内实现,可作为人工电磁媒质设计的通用晶元。更多还原

【Abstract】 In this paper, a new reconfigurable universal element of metamaterials is presented, which is composed of a split-ring resonator(SRR) and an electric-resonant element(ELC). Two ideal switches are used to control the electric and magnetic resonant behaviors, respectively. By adjusting the switches ON or OFF, we can realize the conversion among different functional materials, such as double positive materials(DPM), electric negative materials(ENM), magnetic negative materials(MNM), and double negative materials(DNM). By using optimal design, we can control the different functional materials to work at the same frequency band, which can be used as a universal element for various metamaterial designs.更多还原
