    "abstract": "We discuss how a three level system can be used to change the frequency\ndependent magnetic permeability of an atomic gas to be significantly different\nfrom one. We derive the conditions for such a scheme to be successful and\nbriefly discuss the resulting macroscopic electrodynamics. We find that it may\nbe possible to obtain left handed electrodynamics for an atomic gas using three\natomic levels.",
