As a new power transmission technology, magnetically coupled resonant wireless power transmission technology can achieve mid-range wireless power transmission with the advantage of high transmission efficiency. As known, the driving source has a significant impact on the overall performance of wireless power transmission system. With this consideration, a pulse-driven magnetically coupled reson...

This article re-examines the Brillouin flow solutions in crossed-field diodes, with applications to magnetrons, magnetically insulated line oscillators (MILOs), and transmission lines (MITLs). The are constructed for various geometries, including planar MILOs, MITLs, cylindrical magnetrons electrons flowing azimuthal direction, MITLs MILOs axial radial direction. A common theme of this analysis...

A new nanomotor-based surface-patterning technique based on the movement of a magnetically powered enzyme-functionalized flexible nanowire swimmer offers the ability to create complex helical metal microstructures.

Although representing a 'thermodynamic sink', the octahedral oxozirconium {Zr(6)O(4)(OH)(4)} cluster structure can be magnetically functionalized by up to six 3d metal cations with a combination of flexible aminoalkoxide and carboxylate ligands.

A novel magnetically recoverable Au nanocatalyst was fabricated by spontaneous green synthesis of Au nanoparticles on the surface of gum arabic-modified Fe3O4 nanoparticles. A layer of Au nanoparticles with thickness of about 2 nm was deposited on the surface of gum arabic-modified Fe3O4 nanoparticles, because gum arabic acted as a reducing agent and a stabilizing agent simultaneously. The resu...

We present a method to calculate the electric (E)-fields within and surrounding a human body in a gradient coil, including E-fields induced by the changing magnetic fields and "conservative" E-fields originating with the scalar electrical potential in the coil windings. In agreement with previous numerical calculations, it is shown that magnetically-induced E-fields within the human body show n...

Magnetically controlled shape memory alloy (MSMA) is a new functional material which is found in recent years. The material can produce large induced strain by magnetic field, and has fast dynamic response, high efficiency of electromagnetic-mechanical conversion and excellent controllability. High strains of 10-15% for MSMA materials with different structure are achieved [1, 2]. The complete f...

Magnetically-actuated Micromirrors as Micro-electromechanical devices have exhibited their superiority over other magnetic sensing techniques in terms of high sensitivity and high spatial resolution, which is favoured not only by quantitative measurement but also imaging of magnetic field distribution. In our research into magnetic field sensing and imaging, a 2D magnetic field sensing system w...

A thin cut made through a z-pinch by an intense laser beam can become a magnetically insulated diode crossed by an intense ion beam. For larger cuts, the gap is crossed by an intense relativistic electron beam, stopped by magnetic bremsstrahlung resulting in a pointlike intense x-ray source. In either case, the impedance of the pinch discharge is increased, with the power delivered rising in th...

In magnetically confined plasma research, the understandings of small and large perturbations at equilibrium are both critical for plasma controlling and steady state operation. Numerical simulations using original MHD model can hardly give clear picture for small perturbations, while non-conservative perturbed MHD model may break conservation law, and give unphysical results when perturbations...
