... 2007. ... A required switch must transmit a signal without losses in the open state and completely reflect it in the closed state. This property is ensured if the impedance of the switching element is much larger than the impedance of the line in the open state and is much smaller than the impedance of the line in the closed state. ...

... Microbridges 0.85ґ6.00 ?m in width, intersecting the bicrystalline interface, are formed in epitaxial bicrystalline MgB2 films grown on these substrates. It is found that annealing of bicrystalline samples in oxygen leads to a systematic decrease in the critical current, an increase in the temperature width of the superconducting transition region, and to an improvement of the currentґvoltage (IV) characteristic, which becomes close in shape to the IV characteristic of a Josephson junction. ...

... A Flux-Flow Oscillator (FFO) is a long Josephson junction in which a unidirectional flow of magnetic flux quanta is maintained by an applied DC magnetic field and a bias current. In the overlap geometry the FFO voltage and thus its oscillation frequency is controlled independently by the (overlap) bias current and the so-called "control line" (inline) current, which creates the magnetic field at the ends of the FFO. ... A simplified 3D layout of the FFO with the four current terminals. ...
