Abstract

Artificially synthesized electromagnetic metamaterials can realize the unique properties that are not possessed by natural media in nature, and have broad application prospects in related fields. The zero-refractive index metamaterial is a metamaterial whose relative permittivity or relative permeability is zero through artificial design. It has infinite wavelength, uniform field effect, high directivity radiation, wavefront control and other properties. This paper theoretically analyzes the influence of the structural parameters of the material on the transmission coefficient, and uses software to simulate the electric field distribution of electromagnetic waves passing through the material. The transmission phenomena of single zero and double zero refractive index metamaterials are numerically simulated, and the reasons for this phenomenon are explained. The research results can be used in optical device design and civilian related fields.
