Wireless power transmission coil device based on meta-material

The invention provides a wireless power transmission coil device based on meta-material, the device comprises a transmitting coil, a receiving coil and a conical displacement medium shell, and the conical displacement medium shell wraps the transmitting coil or the receiving coil in an air chamber of the shell; the distance between the transmitting coil and the receiving coil is greater than the diameters of the transmitting coil and the receiving coil separately; the conical displacement medium shell comprises a bottom shell and a side shell; and the bottom shell and the side shell respectively comprises various kinds of uniform and isotropous magnetic material layers. The conical displacement medium shell can optically moves a coil in the air chamber to a specified position on the outside of the shell, that is, the relative position between the transmitting coil and the receiving coil can be changed, so that the mutual inductance and the magnetic coupling of the transmitting coil and the receiving coil can
