In terms of high-current measurement capacitors, PCB Rogowski coils have attracted much attention because their small size and easy installation. However, they are vulnerable to electromagnetic interference. order improve the immunity coil, this paper studies influence structure parameter changes double-layer coil on accuracy mutual inductance. By testing frequency response four common structur...

In this paper, a precorrected-FFT approach for fast and highly accurate simulation of circuits with on-chip inductance is proposed. This work is motivated by the fact that circuit analysis and optimization methods based on the partial element equivalent circuit (PEEC) model require the solution of a subproblem in which a dense inductance matrix must be multiplied by a given vector, an operation...

In this paper, a sensorless rotor posture detection method based on the mutual inductance voltage of stator coil is proposed to simplify position element reluctance spherical motor. Firstly, numerical relationship between stator/rotor pole misalignment angle and analyzed, which used as basis for judging spatial rotor. Secondly, an experimental platform designed verify consistency calculated val...

We measure the dispersive energy-level shift of an LC resonator magnetically coupled to a superconducting qubit, which clearly shows that our system operates in the ultrastrong coupling regime. The large mutual kinetic inductance provides a coupling energy of ≈ 0.82 GHz, requiring the addition of counter-rotating-wave terms in the description of the Jaynes-Cummings model. We find a 50 MHz Bloch...

The ability to switch the coupling between quantum bits (qubits) on and off is essential for implementing many quantum-computing algorithms. We demonstrated such control with two flux qubits coupled together through their mutual inductances and through the dc superconducting quantum interference device (SQUID) that reads out their magnetic flux states. A bias current applied to the SQUID in the...
