This is termed a dispersion relation. While dispersion relationships4 vary with material and situation, they all have the form ω=ωk→ when thinking in terms of waves and the form E=Ek→ when thinking in terms of photons. In general, they may be single valued or multivalued; they may ...
(7). The key point to derive the dispersion relation is to analyze acoustic pressure wave propagation in the tubes. As one example, we consider the tube that connects the cuboid compartment at site (m,n) to its Nth nearest neighbor along x-direction at site (m+N,n). The pressure ...
摘要: The observation of a dispersive effect on the nonlinear generation of ion‐acoustic wave harmonics is reported. This effect is a spatial beat modulation of the second harmonic with a beating length L given by the dispersion: L=2π/[K (2ω)−2K (ω)]. DOI: 10.1063/1.861487 被引...
(Supplementary Fig. 7). The transmission performance of acoustic waves through the two samples are measured with a lab-made standing wave tube system (Supplementary Figs 4 to 5 and Note 2). We made sure that the largest thread lead of the metamaterial samples is smaller than 1/7 of the ...

Experimental determination of ion acoustic wave dispersion relation with interferometric analysis In this paper we study electrostatic waves with time-dependent frequency features in the terrestrial foreshock. These short (0.1-0.3 s) duration waves are ... D Vech,DM Malaspina,C Cattell,... - 《Jo...
waves over arbitrary bathymetry. Applications to four demanding non-linear problems demonstrate the efficiency and the robustness of the present approach. Specifically, we consider the classical tests of strongly non-linear steady wave propagation and the transformation of regular waves due to trapezoidal...
Fig. 18(b) shows the dispersion relations of elastic waves for the binary chains based on the acoustic branch with Rd = D/d = 1, 3, 6, 12, and 25. These Rd values approximately correspond to the experimental cases, where D is kept constant, but d is varied in order to achieve ...
Since the output voltage is proportional to the power densities of the two waves, waveguides are used to improve the operation. Two device properties are essential to the operation of the convolver device 60; these are that the dispersion is flat over the frequency range of interest and that ...
