中文摘要： 非接触式电能传输技术（CETT）可实现"无线"供电的优点引起了人们的广泛关注和研究热情。目前，主流非接触电能传输技术包括基于近场电磁感应原理和基于近场耦合磁共振原理的两种技术。本研究基于耦合模理论、电路理论、电磁场理论，完善电磁感应原理中的互感量或耦合磁共振原理中的耦合系数的数学模型，提出一个能统一两种主流技术的广义模型，并给出广义模型演化为两类主流模型时的临界条件，在完善CETT的理论体系方面进行探索。在此广义模型的基础上，利用完美透镜或超散射体概念，引入人工负折射率超颖材料技术，完成一维、二维超颖材料中继装置的理论分析、设计计算及实验验证，最终达到缩短非接触电能传输系统原、副边线圈的等效距离，从而增加实际传输距离、提高传输效率的目标。

英文摘要： Contactless Energy Transfer Technology can supply power "wirelessly", which causes the people's concern and encourages researching enthusiasm. At present, Electromagnetic Induction Theory (EMIT) and Coupled Magnetic Resonances Theory (CMR) are two mainstream technologies used in the Contactless Energy Transfer System. This research uses Coupled Mode Theory (CMT), Theory of Circuit and Theory of Electromagnetic Field to complete the mathematical model of the mutual inductance in EMIT or the coupling coefficient in CMR. We propose a generalized model to unify the models of the two mainstream technologies and raise critical conditions to transform the generalized model to the two existed models. The research may consummate the theories system of Contactless Energy Transfer Technique. Based on the generalized model, we use the notions of perfect lens or superscatterer and manmade metamaterials to theoretically analyze and calculate as well as experimentally verify the parameters of one-dimensional and two-dimensional metamaterials relay unit. With this method, the equivalent distance of primary and secondary coils in the Contactless Energy Transfer System is shorted and the ultimate goal is to improve the efficiency and increase the real distance of primary and secondary coils in the Contactless Energy Transfer Syst
