Abstract: An imager of a magnetic field includes a sensor array and a display. The sensor array includes sensor pixels, which each include at least one Josephson junction for generating an electrical signal responsive to a magnetic flux of the magnetic field through the sensor pixel. The display is coupled to the sensor array for displaying, for each of the sensor pixels, a respective strength from the electrical signal of the magnetic flux through the sensor pixel.

Abstract: Aspects of the present disclosure relate to receiving and emitting Terahertz (THz) electromagnetic radiation via one or more Josephson Junction(s) electronically coupled to an antenna structure. Aspects of the present disclosure further relate to a mechanism and methods to analyze a gas and/or identifying a gas (and/or suspension) based its electromagnetic absorption. Together, THz electromagnetic radiation may be emitted from one or more Josephson Junction emitters (transmitters), passed through a gas/suspension of interest, and non-absorbed THz electromagnetic radiation may be detected from one or more Josephson Junction detectors (receivers).

Abstract: Aspects of the present disclosure generally pertain to a magnetic field sensor with flex coupling structures. Aspects of the present disclosure are more specifically directed toward Nanoscale Superconducting Quantum Interference Devices (nanoSQUIDs) with very low white flux noise characteristics can be fashioned into very sensitive magnetic field sensors by using external structures to increase the amount of flux that passes through the nanoSQUID aperture. One such structure is a superconducting coupling loop that shares part of a circuit with the nanoSQUID, and couples flux into the nanoSQUID primarily through kinetic inductance rather than geometric inductance.

Abstract: Aspects of the present disclosure relate to a dynamic range module, system and method in general. Aspects of the present disclosure also apply to dynamic range module, system and method implemented into devices benefiting from dynamic range such as radios, radar, test and measurement equipment, and other signals receivers. The dynamic range module uses one or more superconducting quantum interference devices (SQUIDs) to increase the dynamic range of the system.

Abstract: Disclosed is a transceiver that includes a three-dimensional array of Josephson junctions. When transmitting, the junctions drive an array of micro-antennas. When receiving, the micro-antennas drive the array of Josephson junctions. By extending the junction array into the third dimension, this transceiver packages a large number of Josephson junctions into a small volume, thus increasing the power of a transmitted beam. Multiple different micro-antenna arrays can be included, thus allowing the transceiver to work efficiently at multiple frequency ranges.

Abstract: A cavity oscillator comprising: an amplifier operable to provide energy to a local oscillating signal; a superconducting resonant cavity arranged to receive the local oscillating signal and being operable to reflect a portion of the local oscillating signal for use in a feedback circuit, to support an electromagnetic wave related to the local oscillating signal in a desired TM mode, and to output a filtered signal of a desired frequency or frequencies based on the geometry of the cavity; a feedback circuit operable to generate an error signal based on the local oscillating signal and the reflected signal; and a phase shifter arranged operable to adjust the filtered signal based on the error signal to generate an adjusted filtered signal. The amplifier can amplify the adjusted filtered signal.

Abstract: A system and method involve using sferic signals to synchronize clocks and/or determine relative receiver positions within a communications network. A sferic signal is detected, encoded, and then identified. A time-difference-of-arrival (TDOA) for the sferic signal is then calculated. A clock error estimate is determined from the TDOA. The clock error estimate is then used to synchronize clocks and/or determine relative receiver positions.
