Abstract
We propose a superconducting metamaterial design consisting of meta-atoms (MAs) which are each composed of a direct current (dc) superconducting quantum interference device (SQUID) and a superconducting rod. This design provides negative refraction index behavior for a wide range of structure parameters.
