   Abstract:
   We first theoretically present a magnetic antenna based on a two dimensional DC superconducting quantum filter device. This antenna may detect the dynamical magnetic field instead of the absolute magnetic field. We call it B-antenna since it only responses to the external magnetic field. We show the robustness of 2D SQIF structure when the 2D SQIF chip encounters statistical distributions of the fabrication of individual Josephson junctions. Finally, we find that B-antenna can work properly even though the bias current is smaller than the critical current. Our research opens the dimensions of novel ultra-sensitive antennas by combing superconducting quantum interference filter devices and classic electromagnetic waves. © 2013 IEEE.
