Optimization of Magnetic Coupling Resonance Coils
2021 IEEE 16th Conference on Industrial Electronics and Applications (ICIEA), 2021In 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 ...

A Motor Design Based on Wireless Magnetic Resonance Coupling Technology
European Conference on Cognitive Ergonomics, 2020A major challenge of motor design for applications like electric vehicle and aircrafts is to make it light weight. Conventionally electric motors are mailnly made of an iron core, thick wire windings and a magnet. This paper proposes a novel motor design

Constructive combination of resonant magnetic coupling and resonant electrical coupling
2015 IEEE Wireless Power Transfer Conference (WPTC), 2015In 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.

Resonant magnetic coupling indoor localization system
Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication, 2013Building 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.

Investigation of magnetic resonance coupling circuit topologies for wireless power transmission
Microwave and optical technology letters (Print), 2019Magnetic resonance coupling circuits have four general topologies; however, there is a lack of comprehensive theoretical analysis with experimental verification for each of these topologies regarding their attractiveness for wireless power transfer (WPT).

Flexible Induction Heating Using Magnetic Resonant Coupling
IEEE Transactions on Industrial Electronics, 2017This 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.

Nuclear magnetic resonance spectroscopy. Carbon-carbon coupling
Journal of the American Chemical Society, 1972One-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.

Parametric resonance of a magnetically coupled harvester
Active and Passive Smart Structures and Integrated Systems XII, 2018Parametric excitation has been investigated for several years as an effective way to drive a structure parametrically into large distinctive responses. However, parametric resonance requires a minimum threshold of excitation to be triggered. To reduce the threshold, we propose a two-degree-of-freedom vibration system.
