    A new DC-SQUID is proposed that exploits the properties of the grain boundary junctions in high Tc superconductors. The orientations of the grain boundaries are chosen in such a way to establish a π/2 (rather than 0 or π) phase difference between the equilibrium phases of the two Josephson junctions in the SQUID loop. This property is exploited to increase the sensitivity and dire... View full abstract»

    This paper presents a high-speed low-power 4-bit superconducting serial-to-parallel converter (SPC) that has been demonstrated experimentally to operate at data rates up to 1 Giga-bits (Gb/s). The primary design goals for this device are high-speed operation, low-power dissipation, and high circuit yield for use as a core element in an address decoder or a demultiplexer. First, the circuit design ... View full abstract»

    Current injection is a method to compensate for field drift in persistent nuclear magnetic resonance spectrometer magnets by the direct introduction of incremental current into the magnet through leads attached across a portion of the windings. An applied current ramp will distribute among the sections of the windings defined by the placement of the leads according to the inductance of the circuit... View full abstract»

    Ellipsoidal harmonics are presented as a basis function set for the design of shim coils for magnetic resonance imaging (MRI) or spectroscopy. MR shim coils may be either superconductive or resistive. Ellipsoidal harmonics form an orthogonal set over an ellipsoid and hence are appropriate in circumstances where the imaging or spectroscopic region of a magnet more closely conforms to an ellipsoid r...

    A practical design technique for a compact forward-coupled microstrip bandpass filter structure is introduced based on a computer-aided simulation and optimization software TUMIC. The structure consists of a parallel array of fully aligned half-wavelength resonators. Aimed at the application in the front-end receiver of a GSM base station, a 9-pole high-temperature superconductor filter with 2.6% ... View full abstract»
