Abstract

Enclosed is a zero-refraction microwave lens based on an electromagnetic double resonance structure. The zero-refraction microwave lens based on the electromagnetic double resonance structure is used for solving a problem of poor improvement effect of the existing zero-refraction lens with anisotropy to the antenna gain. N+1 secondary strip-type dielectric substrates and N primary strip-type dielectric substrates are alternately arranged in a mutually parallel manner at distances of d 1, d 2, d 1, d 2......d2. The primary strip-type dielectric substrates are etchingly made of the strip-type dielectric substrates with both sides coated with copper. A plurality of split ring resonators SRR with square openings are etched on both surfaces of each strip-type dielectric substrate and arranged along the longitudinal direction of each strip-type dielectric substrate. The shapes of the split ring resonators SRR with the square openings on one surface of each strip-type dielectric substrate are formed by rotating the split ring resonators SRR with the square openings on the other surface of each strip-type dielectric substrate around the center of the strip-type dielectric substrate. The secondary strip-type dielectric substrates 2 are etchingly made of the strip-type dielectric substrates with single sides coated with copper. The zero-refraction microwave lens based on the electromagnetic double resonance structure is used for assisting to increase the antenna gain.

Description

technical field [0001] The invention relates to a zero-refraction microwave lens, in particular to a zero-refraction microwave lens based on an electromagnetic double resonance structure. Background technique [0002] Metamaterial is a new type of artificial material obtained by periodically or non-periodically arranging basic units with specific geometric shapes. By changing the structure and parameters of the basic unit, the electromagnetic properties of the meta-medium, namely its permittivity and permeability, can be freely controlled. The current permittivity and permeability of supernormal media can be positive, negative or zero, and the two can have the same sign or different signs. Therefore, if a metamaterial with zero permittivity or permeability is constructed, the refractive index of the metamaterial can be zero, that is, a zero refractive index material (ZIM or Zero Refractive Index Metamaterial). In 2002, S.Enoch et al. pointed out that zero-refraction materi...
