A wireless power transfer system with more than one receiver is a realistic proposition for charging multiple devices such as phones and a tablets. Therefore, it is necessary to consider systems with single transmitters and multiple receivers in terms of efficiency. Current offerings only consider single device charging systems. A problem encountered is the efficiency of one receiver can be aff...

This paper presents the evaluation of the magnetic fields and mutual inductance between circular coils arbitrarily positioned in space. Firstly, based on an advanced and relevant model available in the literature, MATLAB code is implemented to evaluate the mutual inductance between circular coils arbitrarily positioned with respect to each other. The computed results are compared with the numer...

As interconnect line width and spacing decreases and operating clock rate increases, interconnect has become a bottleneck in developing high-speed integrated circuits, multichip modules, printed circuit boards, and systems. With small line spacing, mutual capacitance and inductance approach the level of self-capacitance and inductance, and can severely degrade signal integrity. The well-known e...

The related issue of the flow of energy in such circuits as described by the Poynting vector is considered in [1]. Supposing the distance d between the centers of the two coils is small compared to the wavelength λ = 2πc/ω, where c is the speed of light in vacuum, circuit analysis is a good approximation. Writing the self inductance of the two coils as Lp = Ls = L and their mutual inductance as...

The test signal method can be used to measure and model inductance parameters (self and mutual) of a very small interconnect especially in highdensity IC’s by using a test signal (of small known amplitude and frequency) and a D.C. signal along with a Differential circuit. Other measurement techniques such as LCZ and TDR for measuring inductance parameters are faced with limitations of L values ...

The crosstalk noise model for noise constrained interconnects optimization is presented for RC interconnects. The proposed model has simple closed-form expressions, which is capable of predicting the noise amplitude and the noise pulse width of an RC interconnect as well as coupling locations (near-driver and near-receiver) on victim net. This paper also presents a crosstalk noise model for bot...

In this article, we derive low-complexity behavioral analytical models of the mutual inductance between coupling coils wireless power transfer systems (WPTSs), as functions their reciprocal position. These are extremely useful in characterization and design optimization WPTSs. Multiobjective genetic programming algorithm is adopted to generate ensuring an optimal tradeoff accuracy complexity. T...

This paper presents a novel method to calculate magnetic inductance with a fast-computing magnetic field model referred to as the extended distributed multi-pole (eDMP) model. The concept of mutual inductance has been widely applied for position/orientation tracking systems and applications, yet it is still challenging due to the high demands in robust modeling and efficient computation in real...
