Incoherent magnetism
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. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow … 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, … See more The coherence of two waves expresses how well correlated the waves are as quantified by the cross-correlation function. Cross-correlation quantifies the ability to predict the phase of the second wave by knowing the phase of the first. As an example, consider … See more Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times. Temporal coherence tells us how monochromatic a source is. In other words, it characterizes how well a wave can interfere with … See more Waves of different frequencies (in light these are different colours) can interfere to form a pulse if they have a fixed relative phase-relationship … See more The coherence function between two signals $${\displaystyle x(t)}$$ and $${\displaystyle y(t)}$$ is defined as $${\displaystyle \gamma _{xy}^{2}(f)={\frac { S_{xy}(f) ^{2}}{S_{xx}(f)S_{yy}(f)}}}$$ where See more These states are unified by the fact that their behavior is described by a wave equation or some generalization thereof. • Waves … See more In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions. Spatial coherence describes the ability for two points in space, x1 and x2, in the extent of a wave to interfere, when averaged over time. More precisely, the spatial … See more WebJan 27, 2024 · To investigate the evaluation value of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) on the early efficacy of magnetic resonance-guided high-intensity focused ultrasound (MRgFUS) ablation for uterine adenomyoma.
