Abstract

The invention relates to a non-radioactive wireless electric energy transmission system based on an electromagnetic tunneling effect in a Meite material. The system comprises an energy generator, a magnetic single negative Meite material, an electric single negative Meite material and an energy receiver. The system can control the amplitude and spatial distribution of an electromagnetic field. The transmission efficiency of the system is not significantly changed with the increase of a distance. The system can realize real-time transmission, namely when a receiving end is closed, a transmitting end can immediately sense the closure and stops the conveying of energy immediately. The system has very good directionality, and the energy is only transmitted to the direction of the receiving end. The single negative Meite materials in the system have sub wavelength characteristics. Compared with the prior art, the system has the advantages of instant transmission, orientation, controllability, no radiation, miniaturization, high efficiency, long distance, no radiation, simple process, low cost and the like.

Description

technical field

[0001] The present invention relates to a wireless power transmission system, in particular to a non-radiative wireless power transmission system based on the electromagnetic tunneling effect in Meite materials. Background technique

[0002] The short-distance energy transmission realized by electromagnetic induction has actually existed for a long time, and its typical application is a transformer device formed by winding two sets of non-contact wires on the same iron core frame. The bus card, meal card, and even the second-generation ID card that we commonly use now have a similar mechanism: a high-frequency magnetic field will be generated around the card reader, and once the chip enters the coil around it, an induced voltage will be generated, thereby activating the chip and The carried information is transmitted through the coil and received by the card reader. In addition, some current wireless charging devices are also based on the same principle of e...
