Optimization of Magnetic Coupling Resonance Coils

2021 IEEE 16th Conference on Industrial Electronics and Applications (ICIEA), 2021
In some practical applications of low-power coupled resonant wireless power transmission, besides the transmission efficiency, the anti-radial offset ability of the transceiver coils is also an important parameter to measure system performance. Consider that the positive correlation between the transmission efficiency and coupling coefficient of the ...

Constructive combination of resonant magnetic coupling and resonant electrical coupling

2015 IEEE Wireless Power Transfer Conference (WPTC), 2015
In this paper the possibility of combining resonant magnetic coupling and resonant electrical coupling is proposed and discussed. Equivalent circuit models are used to demonstrate that efficiency can be improved quite significantly using a hybrid approach.

Nuclear magnetic resonance spectroscopy. Carbon-carbon coupling

Journal of the American Chemical Society, 1972
One-bond, carbon-carbon coupling constants have been observed for several series of compounds containing ^(13)C in its natural abundance of 1.1% at both sites. The small (10-15 Hz) coupling constants in cyclopropanes show that the carbon-carbon bonds have low s character.

Flexible Induction Heating Using Magnetic Resonant Coupling

IEEE Transactions on Industrial Electronics, 2017
This paper proposes and implements the concept of flexible induction heating based on the magnetic resonant coupling (MRC) mechanism. In conventional induction heating systems, the variation of the relative position between the heater and workpiece significantly deteriorates the heating performance.

Magnetic resonant coupling for magnetic induction wireless communication

IETE Journal of Research, 2013
AbstractIn the last decade, magnetic induction (MI) communication has drawn the attention of researchers to alternate the EM communication in some environments, such as the underground environment, littoral environment, underwater environment, and caves.

Nuclear magnetic resonance coupled microseparations

Magnetic Resonance in Chemistry, 2005
AbstractThe increased separation efficiency afforded by reducing the size of the separation column has resulted in ‘microseparations’ becoming an important component in many chemical and biochemical applications. The coupling of microseparations with NMR detection is an area of increasing interest owing to the high structural information of NMR.

Resonant magnetic coupling indoor localization system

Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication, 2013
Building on previous work that introduced a novel indoor positioning concept based on magnetic resonant coupling we describe an improved system to be shown during the UBICOMP 2013 demo session. We improved the magnetic field model, implemented a particle filter for position estimation and a software suite for configuration and calibration of the system.

Magnetic Resonance Coupling Systems

2020
A magnetic resonance coupling circuit is a circuit topology (circuit structure) that can achieve high efficiency and high power even in the presence of large air gaps. However, when considering the design of these systems, it is important to achieve both high efficiency and the desired power simultaneously.

Ferromagnetic resonance of exchange-coupled magnetic layers

Physical Review B, 1988
The ferromagnetic resonance-line shapes, fields, and intensities of exchange coupled magnetic multilayers are calculated as a function of exchange coupling and number of layers. We find that the number of magnetic excitations equals the number of layer pairs that make up the layered structure.
