Abstract


This paper describes the fundamental nature of the course of development of a negative index of refraction of left-handed materials , negative refractive index several common methods of left-handed materials ( artificial composite photonic crystal structure and coherent atomic gas method) , as well as a description of light and the three representation theory of the interaction between light and electromagnetic induction transparency phenomenon. We are given a negative refractive index of the left-handed materials , namely the use of the incoherent pump and strong coherent coupling field effectively control the optical properties of the dielectric permittivity and magnetic permeability . Our theoretical derivation and numerical analysis show that the control incoherent pump rate and a strong coherent coupling field Rabi frequency parameters can be obtained at the same time within a certain frequency range negative refractive index materials characteristic of the left hand ( negative permittivity and negative magnetic conductivity ) , and the left hand in order to achieve a negative refractive index material .
