    "abstract": "A scheme of left-handed metamaterial (LHM) composed of superconducting\nquantum interference devices (SQUIDs) and conducting wires is proposed. The\npermeability of a probe field can be smoothly tuned over a wide range with\nanother electromagnetic (coupling) field due to quantum interference effect.\nSimilar to electromagnetically induced transparency (EIT) of atomic systems,\nthe absorption of the probe field can be strongly suppressed even in the case\nof negative permeability. There are two passbands of negative refractive index\nwith low loss, which can be tuned with the coupling field.",
