IEEE Journal of Microwaves, 2021 Ferromagnetic materials, such as ferrites, are employed for magnetically tuned radio frequency (RF) circuits. Ferrites exhibit both electric permittivity and magnetic permeability and independent RF characterization of these two properties is crucial for

Plasma response to externally applied resonant magnetic perturbations [PDF]
Nuclear Fusion, 2011 Based on recent finding that applied resonant magnetic perturbation (RMP) can either increase or decrease the local electron density gradient around the resonant surface (Yu and Günter 2009 Nucl. Fusion 49 062001), the plasma response to the RMP of a single helicity is studied numerically by further taking into account the ...

Penetration properties of applied resonant magnetic perturbation in HL-2A tokamak
Nuclear Fusion, 2023 Any arbitrary perturbation on a magnetic field separatrix can cause a structure named homoclinic tangle in tokamaks. Both an edge localized mode (ELM) and a resonant magnetic perturbation (RMP) can lead to a perturbation of the magnetic field on the ...

Nuclear Fusion, 2022 The divertor biasing technique offers a promising alternative to control the edge localized mode (ELM) as well as the divertor heat load in tokamaks, as compared to the resonant magnetic perturbation (RMP) generated by magnetic coils.

Disruption prevention using rotating resonant magnetic perturbation on J-TEXT
Nuclear Fusion, 2020 Major plasma disruption is one of the most critical issues to be solved for tokamak fusion reactors. Experiments to prevent mode locking and subsequent disruptions have been carried out on the J-TEXT tokamak using rotating resonant magnetic perturbations

Effect of resonant magnetic perturbations on particle confinement [PDF]
Nuclear Fusion, 2009 The effect of externally applied resonant magnetic perturbations (RMPs) on plasma particle transport is investigated based on two fluid equations. It is found that, depending on the frequency and direction of plasma rotation, the RMP of a moderate amplitude can either increase or decrease the plasma density gradient around the corresponding rational ...

Control of Transport-Barrier Relaxations by Resonant Magnetic Perturbations
Physical Review Letters, 2009 Transport-barrier relaxation oscillations in the presence of resonant magnetic perturbations are investigated using three-dimensional global fluid turbulence simulations from first principles at the edge of a tokamak. It is shown that resonant magnetic perturbations have a stabilizing effect on these relaxation oscillations and that this effect is due ...

Perturbation approach for nuclear magnetic resonance solid‐state quantum computation [PDF]
Journal of Applied Mathematics, 2003 A dynamics of a nuclear‐spin quantum computer with a large number (L = 1000) of qubits is considered using a perturbation approach. Small parameters are introduced and used to compute the error in an implementation of an entanglement between remote qubits, using a sequence of radio‐frequency pulses.
