Patent number: 10295614Abstract: The transfer function of a sensing device including a plurality of sensors is automatically adjusted based on a power level of an incident electromagnetic signal detected by the plurality of sensors. Each of the plurality of sensors is associated with a unique transfer function. An output from one of the plurality of sensors associated with a particular transfer function is automatically selected based on a power level of the detected incident electromagnetic signal. Responsive to a change in the power level of the detected electromagnetic signal, another output from a different one of the plurality of sensors associated with a different transfer function is selected. The transfer function is adjusted over time by automatically selecting outputs from different ones of the plurality of sensors based on changes in the power level of the detected incident electromagnetic signal.Type: GrantFiled: September 14, 2017Date of Patent: May 21, 2019Assignee: The United States of America as represented by the Secretary of the NavyInventors: Anna M.

Patent number: 10274548Abstract: A device in accordance with several embodiments can include a plurality of N Superconducting Quantum Interference Devices (SQUIDs), which can be divided into a plurality of sub-blocks of SQUIDs. The SQUIDs in the sub-blocks can be RF SQUIDs, DC SQUIDs or bi-SQUIDs. The sub-blocks can be arranged in a plurality of X tiers, with each Ti tier having a different number of sub-blocks of SQUIDs than an immediately adjacent Ti tier. Each Ti tier can have the same total bias current; and can have SQUIDs with different critical currents and loop sizes, with the different loop sizes on each tier having a Gaussian distribution of between 0.5 and 1.5 (or a random distribution). Additionally, the Arrays can be configured as three independent planar arrays of SQUIDs. The three planar arrays can be triangular when viewed in top plan, and can be arranged so that they are orthogonal to each other.Type: GrantFiled: August 8, 2016Date of Patent: April 30, 2019Assignee: United States of America as represented by the Secretary of the NavyInventors: Susan Anne Elizabeth Berggren, Robert Lewis Fagaly

Patent number: 10234514Abstract: An antenna includes a plurality of superconducting quantum interference device (SQUID) arrays on a chip, and a printed circuit board (PCB) formed with a cutout for receiving the chip. The PCB is formed with a set of coplanar transmission lines, and the chip is inserted into the cutout so that each said transmission line connects to a respective SQUID array. A cryogenic system can cool the chip to a temperature that causes a transition to superconductivity for the SQUID arrays. A thermal radome can be placed around the chip, the PCB and the cryogenic system to maintain the temperature. A DC bias can be applied to the SQUID arrays to facilitate RF detection. The SQUID array, chip and CPW transmission lines can cooperate to allow for both detection of said RF energy and conversion of said RF energy to a signal without requiring the use of a conductive antenna dish.Type: GrantFiled: November 23, 2016Date of Patent: March 19, 2019Assignee: The United States of America, as Represented by the Secretary of the NavyInventors: Anna M.

Patent number: 10175308Abstract: A High Temperature Superconducting (HTS) Superconducting Quantum Interference Device and methods for fabrication can include at least one bi-Superconducting Quantum Interference Device. The bi-SQUID can include an HTS substrate that can be formed with a step edge. A superconducting loop of YBCO can be deposited on the step edge to establish two Josephson Junctions. A superconducting path that bi-sects the superconducting loop path can also be deposited onto the substrate. In some embodiments, the bisecting path can cross the step edge twice, and the bisecting path can be ion milled at one of the crossing points to round the bisecting path and thereby remove the fourth Josephson Junction at the other crossing point. In still other embodiments, the bisecting path can be completely on the upper shelf (or the lower shelf), and the bisecting path can be ion damaged, ion damaged, or particle damaged, to establish the third Josephson Junction.Type: GrantFiled: August 22, 2018Date of Patent: January 8, 2019Assignee: The United States of America, as Represented by the Secretary of the NavyInventors: Susan Anne Elizabeth Berggren, Benjamin J.

Patent number: 10177298Abstract: A Josephson junction device and methods for manufacture can include an untwinned YBa2Cu3Ox nanowire having crystallographic a- and b-axes. The nanowire can be established from YBa2Cu3Ox film (6.0?x?7.0) using a photolithography process, followed by an ion milling process, to yield the YBa2Cu3Ox nanowire. The crystallographic b-axis of the nanowire can be parallel to the long dimension of the nanowire. First and second gate structures can be placed on opposite sides of the nanowire across from each other, to establish first and second microgaps. A gate voltage can be selectively applied across the first and said second gate structures, which can further establish a selective electric field across the first and second microgaps. The electric field can be parallel to the nanowire crystallographic a-axis, to selectively cause an at will Josephson junction effect.Type: GrantFiled: September 26, 2017Date of Patent: January 8, 2019Assignee: The United States of America as represented by the Secretary of the NavyInventors: Benjamin J.
