In this study, we investigate synchronization phenomena in coupled polygonal oscillatory networks with strong frustrations. We focus on the amplitude of each oscillator when the coupling strength is increased. By using the computer simulations, we confirm that the amplitude of the oscillators decreases by increasing the coupling strength and oscillation death frustrated oscillators is occurred. Furthermore,...
The misalignment of the transmitting and receiving coils in a wireless inductive link can degrade the link efficiency and limit the amount of power transfer. A coil structure, which is composed of two orthogonally-placed windings for the receiver, will be presented. Such structure lessens the variation of the coupling between the transmitting and receiving coils under coil misalignment. A canonical...
For the last two decades, significant improvements in charging technologies have been made. Moreover, novel applications have been proposed and tested, obtaining important and promising results. Inductive charging for electric vehicles (EV) and hybrid electric vehicles (HEV) is one of them. Because of the positive impact that this technology represents, it is important to understand the general characteristics...
This paper shows an accurate crosstalk noise analysis for RLCG on-chip VLSI global interconnects and also presents a fast response and accurate estimation of crosstalk noise generated due to coupling effect in multiple RLCG transmission lines. Due to the coupling effect, the performance of interconnect is degraded. This degradation is seen by the electronic design automation (EDA) tools. This RLCG...
In this study, we investigate synchronization phenomena in coupled chaotic circuits with different coupling strength when chaotic circuits are arranged irregularly in one dimensional array. Three groups are composed in this circuit system and each group includes some chaotic circuits. The coupling strength corresponds to the distance between the chaotic circuits. We observe several types of clustering...
Increases in printed circuit board (PCB) cost is leading to denser routing of high speed signal traces and this, in turn, is increasing the crosstalk among the traces. The crosstalk between the broadside coupled traces in adjacent layers is becoming an important factor to account for as the signal speeds increase. The coupling between parallel broadside coupled traces can be modeled using multi-conductor...
An efficient analysis of the capacitive via-plate coupling in multilayer printed-circuit board (PCB) structures is presented. The quasistatic solution for the via-plate capacitance is determined as the solution of Laplace's equation for the static electric potential within the via-plate region, which is electrically small for a large frequency range. The final capacitance solution can be obtained...
In this study, we investigate synchronization phenomena in coupled chaotic circuits which are connected with distance information. We confirm that the chaotic circuits arranged in the near distance are synchronized at in-phase state, and the coupled circuits with the far distance could not be synchronized. Namely, clustering phenomena of coupled chaotic circuits is observed on two-dimensional place.
This study considers two models in the z-direction displacement for an atomic force microscope (AFM), in which one was modeled without the coupling effect and another one was modeled being coupled with the x and y directions. The modeled AFM is a commercial type NT-MDT as the same one used in [1]. The piezoelectric tube scanner in the z-axis has the different dynamics behavior comparing with the piezoelectric...
Proton exchange membrane fuel cells (PEMFC) can be considered as low voltage sources, so that most of time, they are connected to power electronic converters, such as boost converter, in order to increase voltage levels. In this work, we emphasize another way to use PEMFC as regulated current sources controlled by hydrogen flux. Experiments have been led on a test bench equipped with a PEM single...
In this study, synchronization phenomena observed in coupled polygonal oscillatory networks with frustration is investigated. In this oscillatory system, dilemma is created by the shared branch. We investigate the phase difference between adjacent oscillators when the number of oscillators connected to one side of the polygonal network is increased for considering the large-scale oscillatory networks.
The development of nanostructures as components of macroscopic electrical circuits puts into evidence the necessity of providing integrated models of the entire system. The most natural approach is to represent such nanostructures by equivalent circuits to be imbedded in the model of the macroscopic structure. In the paper we discuss to which extent such a task can be accomplished and in particular...
In this paper the time domain modelling of a transmission line coupling by an external EM fields is described. These fields generated by a nearby lightning stroke induced in an electricity transport and distribution power lines. To model this coupling, we have used the equivalent circuit taking in consideration the different physical concepts based on the theoretical Taylor's formulation. The numerical...
While analytical descriptions of the electrical machine perform very well with respect to computational time giving acceptable results when compared to measurements, one may sacrifice the low computational effort in order to obtain more accurate results by including a Finite Element Analysis of the electrical machine. With this approach it is possible to study effects such as saturation and mutual...

A three-phase induction machine is used as example and its field-circuit transient coupling equations are presented. With the Element-Free Galerkin Method (EFGM) the final system of equations is obtained...
In the design process of micro systems their heterogeneity is one major issue. This heterogeneity is caused by a close coupling of different physical effects as well as a strong influence of manufacturing technologies and operation conditions on the system behavior. System level simulation of micro systems features outstanding potentials for a comprehensive design support covering the whole range...
A novel transmission line model was deduced based on the Taylor model. These models are all applied to analysis the induced voltage and current along lines in the field-transmission line coupling problems. Differenting from the former conventional transmission line models, the distributed excitation source terms in this modified model are expressed in total field components rather than incident field...
This present paper is a farther application of earlier investigation of transmission line model relating to the field-transmission line coupling. A modified model was derived before based on the Taylor model, and the distributed excitation source terms in this modified model are expressed in total field components rather than incident field ones. Combined with electrocircuit and electromagnetic simulation...
An equivalent circuit is presented for a quantum system composed of two spin 1/2 particles. Such a circuit shows that the entire dynamics of the system, including single-particle and two-particle annihilation and creation, as well as the single particle transitions between ground and excited states, can be described as the superposition of the variables of two uncoupled resonant circuits.
A new equivalent circuit model for multiple winding transformers is proposed in which the respective winding leakage inductances themselves are treated as coupled inductors with effective coupling coefficients. This new model is called the coupled leakage model.
