Negative Refractive Index in an Inhomogeneously Broadened Four-Level Inverted-Y Atomic Medium

In this paper, we present the study on negative refractive index in an inhomogeneously broadened four-level inverted-Y atomic medium based on electromagnetically induced transparency (EIT). The expressions of the relative permittivity and the relative permeability are derived under Doppler broadenin...
