Synchronization of mutually coupled LC-oscillators

2006 IEEE International Symposium on Circuits and Systems, 2006
It is shown that synchronization is similar to amplitude stabilization: both mechanisms involve creation of harmonics and frequency reduction. Synchronization of LC-oscillators can be achieved using similar synchronizing circuits in each oscillator connected in parallel with the tank.

Mutual and Self-Impedance for Coupled Antennas

Journal of Applied Physics, 1944
A general theory for the current in coupled antennas is formulated in terms of the vector potential and applied to determine the self-impedance Zs1 and the mutual impedance Z12 of a center-driven antenna in the presence of a second parallel, identical antenna which may be center-driven or center-loaded in an arbitrary way.

Sparsity Enhancement in Mutuality Coupled Networks

IEEE Transactions on Power Apparatus and Systems, 1984
Mutual coupling in three-phase or zero-sequence networks often results in severe sparsity degredation in network analyses based on the nodal admittance matrix. Retention of mid-line nodes in the zero-sequence nodal admittance matrix results in sparsity enhancement and computational improvements.

Coupled Mutual Inhibition and Mutual Activation Motifs as Tools for Cell-Fate Control

Cells Tissues Organs, 2022
Multistability is central to biological systems. It plays a crucial role in adaptation, evolvability, and differentiation. The presence of positive feedback loops can enable multistability. The simplest of such feedback loops are (a) a mutual inhibition (MI) loop, (b) a mutual activation (MA) loop, and (c) self-activation.

Impact of Mutual Coupling on MIMO Channel Modelling

2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007
Mutual coupling effect between antennas on MIMO (multiple input multiple output) transmission is an important factor to take into account for an accurate modelling channel when antennas are closely spaced. The aim of this paper is to present the impact of mutual coupling on MIMO channel characteristics according to several propagation contexts.

Applications of Mutually Coupled Reactor

IEEE Transactions on Power Apparatus and Systems, 1984
A new device of mutually coupled series reactor is proposed. Analytical and experimental studies on the working models by using the miniature system are conducted. Effects on improvement of stability limits, suppression of fault currents, minimization of shaft torsional responses of the turbine generators, and control of the power flow in a power ...

Noise in Mutually Coupled Oscillators

9th European Microwave Conference, 1979, 1979
A general noise theory for microwave oscillators, which is based upon the describing function method, is developed and applied to the cases of mutually coupled and multiple-device oscillators. Explicit expressions are derived for the output power, the FM-and the AM-noise.

Transient Oscillations of Mutually Coupled Windings

Transactions of the American Institute of Electrical Engineers, 1932
IN THE PAST, the mathematical analysis of transient oscillations in transformer windings has been based upon a single winding having self and mutual inductances between its turns, capacitances along the stack and to ground, and, in one instance, resistances representing the losses.

Synchronization of mutually coupled systems

Optics Communications, 2006
Abstract General operation conditions to obtain anticipated or retarded synchronization in a mutually coupled system with feedback are analyzed. Different from a unidirectionally coupled system, which type of synchronization will occur in a mutually coupled system does not solely depend on the difference between the feedback-delay time and the ...

Leaky and mutually coupled quantum wires

Physical Review B, 1993
In this paper, we investigate the effect on the transport in a quantum wire of short-ranged irregularities in the boundary. The results obtained are generalized to the case of a small hole in the boundary. Via such a hole, the wire is coupled to free two-dimensional space or to a second wire.
