主 题:Negative refractive index Left-handed medium Electromagnetically induced transparency Atomic level Optical frequency
摘 要:The theoretical mechanism for realizing a negative refractive index material in an optical frequency range with an atomic gas system of electromagnetically induced transparency (EIT) is studied. It is shown that under certain conditions such a dense gas can exhibit simultaneously negative permittivity and negative permeability, and negligibly small loss.
