Determination of mutual inductance in the WPT system based on the electromagnetic coupling mode is crucial for system design and efficiency optimization. The analytic formulas and experimental methods which only aim at a coupling coil with a certain type of configuration and parameters are not universal approaches. Therefore they can’t serve as a design basis for the system optimization. This p...

This paper describes a new method for coupling ultrasound images with tree-dimensional electromagnetic data, to recover larger parts of the tongue during speech production. The electromagnetic data is superimposed on ultrasound images after spatial and temporal calibration. Successful fusion results are presented on various speech sequences. A complete setup for evaluation of the electromagneti...

BACKGROUND Electrical stimulation is used to treat nonunions and to augment spinal fusions. We studied the biochemical pathways that are activated in signal transduction when various types of electrical stimulation are applied to bone cells. METHODS Cultured MC3T3-E1 bone cells were exposed to capacitive coupling, inductive coupling, or combined electromagnetic fields at appropriate field str...

In this paper we show that power-law inflation can be realized in non-minimal gravitational coupling of electromagnetic field with a general function of Gauss-Bonnet invariant. Such a non-minimal coupling may appear due to quantum corrections. We also consider modified Maxwell-F (G) gravity in which non-minimal coupling between electromagnetic field and f (G) occur in the framework of modified ...

A relativistic theory for two-stream free electron laser (FEL) with a one-dimensional helical wiggler and ion-channel guiding in the presence of self-fields are presented. A dispersion relation (DR) which includes coupling between the electromagnetic and the electrostatic waves is derived from a fluid model, with all of the relativistic terms related to the transverse wiggler motion. This DR is...

The non-relativistic quantum field theoretic lagrangian which describes an anyon system in the presence of an electromagnetic field is identified. A non-minimal magnetic coupling to the Chern-Simons statistical field as well as to the electromagnetic field together with a direct coupling between both fields are the non trivial ingredients of the lagrangian obtained from the non relativistic lim...

The physical description in itself can be based on the kind of coupling being involved (i.e., thermal, gravitational, electromagnetic, or by matter exchange). Gravitational coupling is related to celestial mechanics and tidal deformation. Thermal coupling is ultimately concerned with energy balance. Matter exchange is concerned with the interaction between contiguous systems, and particularly i...

The effective Hamiltonian formalism is extended to vectorial electromagnetic waves in order to describe statistical properties of the field in reverberation chambers. The latter are commonly used in electromagnetic compatibility tests. As a first step, the distribution of wave intensities in chaotic systems with varying opening in the weak coupling limit for scalar quantum waves is derived by m...
