WebJun 23, 2016 · Chimera patterns, which consist of coexisting spatial domains of coherent (synchronized) and incoherent (desyn- chronized) dynamics are studied in networks of FitzHugh-Nagumo systems with complex topologies. To test the robustness of chimera patterns with respect to changes in the structure of the network, we study the following … WebJun 1, 2012 · The wave fields produced by real sources are neither fully coherent nor completely incoherent but partially coherent. The entropy of partially coherent rays was first investigated by Von Laue [3] . To well address the partial coherence properties, Wolf [4] , introduced the concept of degree of coherence which is the normalized correlation ...

The amount of coherence can readily be measured by the interference visibility, which looks at the size of the interference fringes relative to the input waves (as the phase offset is varied); a precise mathematical definition of the degree of coherenceis given by means of correlation functions. See more In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. … See more Coherence was originally conceived in connection with Thomas Young's double-slit experiment in optics but is now used in any field that involves waves, such as acoustics, electrical engineering, neuroscience, and quantum mechanics. Coherence … See more These states are unified by the fact that their behavior is described by a wave equation or some generalization thereof. • Waves in a rope (up and down) or slinky (compression and expansion) • Surface waves in a liquid See more In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions.
