Contra-directional coupling into slotted photonic crystals for spectrometric applications [PDF]
, 2014 We propose and demonstrate the concept of a contra-directional coupler between a W1 and a slotted photonic crystal waveguide. The bandwidth and operating wavelength of such a coupler can be controlled via its geometrical parameters, and power transfer is

Synchronization by reactive coupling and nonlinear frequency pulling [PDF]
Physical Review E, 2006 We present a detailed analysis of a model for the synchronization of nonlinear oscillators due to reactive coupling and nonlinear frequency pulling. We study the model for the mean field case of all-to-all coupling, deriving results for the initial onset of synchronization as the coupling or nonlinearity increase, and conditions for the existence of ...

The role of the relative voltage and phase for frequency coupling in a dual-frequency capacitively coupled plasma [PDF]
Applied Physics Letters, 2008 Frequency coupling in multifrequency discharges is a complex nonlinear interaction of the different frequency components. An alpha-mode low pressure rf capacitively coupled plasma operated simultaneously with two frequencies is investigated and the coupling of the two frequencies is observed to greatly influence the excitation and ionization within the

A computational study on altered theta-gamma coupling during learning and phase coding [PDF]
, 2012 There is considerable interest in the role of coupling between theta and gamma oscillations in the brain in the context of learning and memory. Here we have used a neural network model which is capable of producing coupling of theta phase to gamma ...

Dynanics of a vehicle-track coupling system at a rail joint [PDF]
, 2015 The dynamic behaviour at a rail joint is examined using a two-dimensional vehicle–track coupling model. The track system is described as a finite-length beam resting on a double-layer discrete viscous-elastic foundation.
