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 ...

Mutual coupling compensation accuracy

IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002
Mutual coupling between array antenna elements degrades the SINR of adaptive algorithms and distorts array transmit and receive patterns. Techniques have been developed to measure the coupling matrix C and to compensate array data using the matrix inverse C/sup -1/.

MISC Array: A New Sparse Array Design Achieving Increased Degrees of Freedom and Reduced Mutual Coupling Effect

IEEE Transactions on Signal Processing, 2019
Recently, nested and coprime arrays have attracted considerable interest due to their capability of providing increased array aperture, enhanced degrees of freedom (DOFs), and reduced mutual coupling effect compared to uniform linear arrays (ULAs). These

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.

Eigenvalue Based Mutual Coupling Reduction

2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring), 2019
This work introduces a novel decoupling technique which employs the theory of coupled characteristic modes for a two element microstrip array. The key idea is to optimize the shape of the decoupling structure using the eigenvalues of the coupled array which can be computed with no prior knowledge of the excitation arrangement.

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 ...

Mutual coupling in phase array

2007 IEEE Antennas and Propagation Society International Symposium, 2007
Phase array systems can be found in military radar, satellite communications, space-time adaptive communications, and MIMO systems. As hardware capabilities increase, it will become feasible to implement MIMO communication systems, which will push further towards the Shannon Channel Capacity. This paper presents a comparison of standard beam formations,

Mutual coupling of shunt slots

IRE Transactions on Antennas and Propagation, 1960
Stevenson's method of analysis is extended to the case of a pair of shunt slots in the broad face of rectangular waveguide. The voltages in the slots are calculated including the effect of mutual coupling. Formulas suitable for calculation of mutual coupling are presented and the results of calculations for certain cases of overlapping quarter-wave ...
