基于负磁和零磁超材料结合的无线输电系统性能提升装置
摘要：
本发明公开了一种基于负磁和零磁超材料结合的无线输电系统性能提升装置，应用于包括发射装置和接收装置的无线电能传输系统，属于无线电能传输性能领域，它包括负磁导率超材料和近零磁导率超材料，其中，负磁导率超材料放置于发射装置和接收装置之间；近零磁导率超材料有两个，分别放置于发射装置的前面和接收装置的后面，用于接收入射的泄露的磁场，并使磁力线发生反射。本发明装置能够可在有效降低无线电能传输系统的磁场泄露的同时，提升系统的传输效率，且易于实施、成本较低。
摘要（英）：

The invention discloses a wireless transmission system performance improvement device based on the combination of negative magnetic field and zero magnetic metamaterial, The invention relates to a radio energy transmission system comprising a transmitting device and a receiving device, belonging to the radio energy transmission performance field, comprising a negative permeability metamaterial anda near-zero permeability metamaterial, wherein the negative permeability metamaterial is disposed between the transmitting device and the receiving device; There are two near zero permeability metamaterials, located in front of the transmitting device and behind the receiving device, for receiving the leaking magnetic field emitted and reflecting the magnetic field lines. The device of the invention can effectively reduce the magnetic field leakage of the radio energy transmission system and improve the transmission efficiency of the system, and is easy to implement and low in cost.
