Magnetic Field of RF Coil Measurement by NMR Method
A spectroscopic imaging technique with high spatial resolution was used for the measurement of the static magnetic field homogeneity of RF coils. Measured magnetic fields of optimised and not optimised saddle-shaped coils were compared with the theoretical calculations. Results are in good qualitative agreement between calculated and measured magnetic field distributions. Quantitative disagreem...
متن کاملA Novel Transformer-Based Single-to-Three Phase Conversion Technique Using Rotating Magnetic Field Theory
This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...
متن کاملRF Field Analysis for High Field Magnetic Resonance Imaging Systems
The combined field integral equation method is used to calculate the RF B1 field produced by a transmission line resonator element for high field magnetic resonance systems. The proposed method provides faster electromagnetic field results than the finite difference time domain approach. A field localization method is also discussed.
متن کاملTransient model of induction machine using rotating magnetic field approach
Most simulation models of electric machines use the coupled circuit approach, where the machine is considered as an electric circuit element with time-varying inductances (abc model) or with constant inductances (dq0 model). On the other hand, the rotating magnetic field approach, which considers the electric machine as two groups of windings producing rotating magnetic fields and can give insi...
متن کاملVacuum Birefringence in a Rotating Magnetic Field
We calculate the vacuum polarization-induced ellipticity acquired by a linearly polarized laser beam of angular frequency ω̄ on traversing a region containing a transverse magnetic field rotating with a small angular velocity Ω around the beam axis. The transmitted beam contains the fundamental frequency ω̄ and weak sidebands of frequency ω̄±2Ω, but no other sidebands. To first order in small quan...
