[0025] Example
[0026] Such as figure 1 As shown, a new type of metamaterial whose equivalent dielectric constant and equivalent permeability are not negative is applied to a wireless energy transmission system to improve the energy transmission efficiency of the system.
[0027] The new material includes a dielectric substrate 1. x*y periodically arranged metal units are symmetrically printed on both sides of the dielectric substrate. X and Y are both natural numbers. The metal unit adopts a four-arm spiral structure 2, and the four The arm spiral structure is a rectangular spiral structure or an annular spiral structure. The four starting arms with the same starting point as the center rotate n times clockwise or counterclockwise at the same time, the angle between adjacent starting arms among the four starting arms is 90 degrees, and the starting points of the four arms are the same. The end points are connected together by short stubs, and a metalized via 3 is punched at the ...
