Embodiment Construction

[0019] "Metamaterial" refers to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature.

[0020] Three important features of "metamaterials":

[0021] (1) "Metamaterials" are usually composite materials with novel artificial structures;

[0022] (2) "Metamaterials" have extraordinary physical properties (often not available in natural materials);

[0023] (3) The properties of "metamaterials" are jointly determined by the intrinsic properties of the constituent materials and the artificial microstructures in them.

[0024] Such as Figures 3 to 4 As shown, the metamaterial zoom lens according to the present invention includes a substrate 1 and a plu...

Abstract

The invention relates to a zoom lens made of super materials. The zoom lens made of super materials comprises a substrate and a plurality of metal micro structures adhered onto the substrate, wherein semiconductor elements are arranged on the metal micro structures, an external interface is reserved on each metal micro structure, and external voltage signals can be loaded on each semiconductor element through the external interfaces. By means of the zoom lens made of super materials, after the external voltage signals can be loaded on the semiconductor elements of the metal micro structures through the external interfaces, electromagnetic parameter distribution (namely refractive index distribution) of the whole super materials is changed, accordingly focal length of the zoom lens made of super materials is changed, and the focal length is accordingly adjusted.

Description

technical field [0001] The invention belongs to the field of metamaterials, and in particular relates to a metamaterial zoom lens. Background technique [0002] In optics, the use of a lens can make the spherical wave radiated by a point light source placed on the focal point of the lens become a plane wave after being refracted by the lens, and vice versa, the plane wave can also be converged at the focal point. The zoom lens in optics is usually implemented by a lens group, changing the relative position of each lens in the lens group can change the focal length of the entire lens group. In the field of electromagnetics (radio frequency microwave, etc.), lens antennas are usually also made of large pieces of dielectric processed into the shape of a convex lens, and there is no related technology with a variable focal length. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metamaterial zoom lens that can flex...
