Abstract
The present invention discloses a structure and method for realizing electromagnetically-induced transparency. In the present invention, a first split-ring resonator and a second split-ring resonator form a resonance structure. The first split-ring resonator and the second split-ring resonator are made of a conductive material. The first split-ring resonator has a 'U' shape with a containing space. The second split-ring resonator has a 'rectangular loop' shape with a gap or has a “U” shape with an opening. The second split-ring resonator is inserted into the containing space with the gap or opening arranged inside the containing space and faced downward to form the resonance structure. The resonance structures are periodically arranged on a chip to form an array. Thereby, different-frequency electromagnetic waves can be used to generate electromagnetically-induced transparency via regulating the dimensions of the resonance structure.
