On the evaluation of mutual coupling between slots
IEEE Transactions on Antennas and Propagation, 1987Analytical expressions for mutual coupling between slots embedded in a large ground plane are presented and discussed, both for piecewise-sinusoidal and for cosinusoidal field distribution. In the former an exact analytical expression has been found; in the latter various approximations based on Taylor and/or Fourier representation, have been analyzed.

Mutual Coupling Calibration for Adaptive Array Based on the Mutual Coupling Grid
2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019A mutual coupling calibration method for the adaptive antenna array is proposed. The method is base on the mutual coupling grid model that is introduced to describe the mutual coupling effect of the adaptive antenna array. On the basis of the gird model, the relationship between the induced terminal voltages due to the elements in the isolated state ...

Wireless Orientation in the Presence of Mutual Couplings
2020 IEEE Radio and Wireless Symposium (RWS), 2020Conventional microwave orientation methods based on the array antenna require high element isolation in most cases. In our work, a neural network-based microwave orientation method is proposed to avoid the interferences caused by the mutual couplings between elements.

On the Dynamics of a Couple of Mutually Interacting Neurons
2013A model for describing the dynamics of two mutually interacting neurons is considered. In such a context, maintaining statements of the Leaky Integrate-and-Fire framework, we include a random component in the synaptic current, whose role is to modify the equilibrium point of the membrane potential of one of the two neurons when a spike of the other one

Eigenvalue Based Mutual Coupling Reduction
2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring), 2019This 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.

Synchronization of mutually coupled LC-oscillators
2006 IEEE International Symposium on Circuits and Systems, 2006It 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.

1967
Abstract : The report gives the complete derivation (in an appendix) of the radiation admittance of a rectangular waveguide acting as an element in an infinite phased array. The derived equations are capable of predicting the experimentally observed anomalous notch that has been found to exist in arrays composed of large waveguides.

Mutual Caring of Elderly Korean Couples
Journal of Transcultural Nursing, 2007The article described the experiences of elderly couples caring for each other using ethnographic methodology. Ten couples were interviewed in depth. The presence of a support system was found to be the primary requirement of elderly couples. Three taxonomies comprised the support system: (a) desire for respect in care, (b) desire for reliance, and (c)

Mutual and Self-Impedance for Coupled Antennas
Journal of Applied Physics, 1944A 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, 1984Mutual 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.
