Claim 0:
1. An electromagnetic lens, wherein the electromagnetic lens is a winded body made of a strip material, a dielectric material is distributed on a surface of and/or inside the strip material, and a dielectric constant of the dielectric material gradually changes in both a transverse direction and a longitudinal direction of the strip material; after the strip material is winded to be the winded body, the dielectric material is distributed in at least one artificially predetermined three-dimensional space range inside the winded body, and the three-dimensional space range with the dielectric material distributed is called a lens body; a part of the winded body besides the lens body is called a non-lens part; the winded body has or does not have the non-lens part; the dielectric constant of the lens body is not lower than the dielectric constant of the non-lens part; the dielectric constant of the lens body gets lower and lower in all directions from inside to outside of the lens body, and each direction from inside to outside of the lens body indicates a direction from a central area of the lens body to a boundary of the lens body.
