A set of transverse momentum injection actuators may be positioned on the surface of the object to affect large-scale eddies in the turbulent boundary layer. The system may include a controller to selectively actuate the transverse momentum injection actuators with an actuation pattern to affect the...
The error bars show the width of the concentric circles in momentum space. e, f Near-field image of the AGPs at −4 V and the corresponding Fourier transform. The wavelength of excitation light is λ = 10.653 μm. Scale bars, 300 nm. Full size image Here, we placed the ...
We consider both coherent (in-plane momentum is conserved) and incoherent (no momentum conservation) c-axis transfers and find that the two cases give quite a distinct c-axis conductivity as a function of energy ω. Comparison of our theoretical calculations with the available data does not ...
polariton propagation length and the directional polariton confinement. This allows for verifying a linear dispersion and elliptical isofrequency contour in momentum space, revealing in-plane anisotropic acoustic terahertz PPs. Our work shows high-symmetry (elliptical) polaritons on low-symmetry (monoclinic...
Space-time-varying materials pledge to deliver nonreciprocal dispersion in linear systems by inducing an artificial momentum bias. Although such a paradigm eliminates the need for actual motion of the medium, experimental realization of ... MA Attarzadeh,J Callanan,M Nouh 被引量: 0发表: 2019年 ...
Generation and regulation (control) of linear and angular momentum is a challenge during turning while walking which may be exacerbated by age-related changes. In healthy older adults, little is known about how momentum is controlled during turns, especially within each phase of gait. Each phase ...

The first term represents the interaction defined in momentum space with the coupling constant J, which consists of the two-spin isotropic exchange interaction and symmetric anisotropic exchange interaction. 𝐼𝛼𝛽𝑸𝜈IQναβ for 𝛼,𝛽=𝑥,𝑦,𝑧α,β=x,y,z represents the 𝑸...
We elaborate on this by presenting the momentum in more detail in Figure 2 and examine a few examples of grating structures that must be avoided for the intended application. Figure 2. Impact of grating geometry: (a) reduced value of the grating vector with two resulting beam pairs; (b) ...
I was making headway. I needed to add to the momentum. “Guess what she did right before the crash?” I said. “She got engaged. To be married. Today is her engagement day. And guess who was flying the plane? Her fiancé—a real wanker, by the looks of things.” ...
