dispersion relation

n
(General Physics) physics the relationship between the angular frequency (ω;) of a wave and the magnitude of its wave vector (k). Thus the wave's speed is ω/k

The response amplitudes are determined by the shape of the perturbation source, on the one hand, and by the solution structure of the dispersion relation D(k, [omega]) = 0, on the other hand.
In case of linear waves, the magnitudes of the maximum amplitudes A and B in (6) are not determined by the dispersion relation, they usually depend on the existence of external forces and in case of the Eastern Baltic on wind conditions.
The second factor of equation (15) equating to zero, we obtain following dispersion relation
Equation (5) then results in the dispersion relation
We also derive a simple dispersion relation of longitudinal plane waves to demonstrate the properties of the constitutive relation.
NIST used this apparatus to measure dispersion relations in several samples including titanium nitride films on single-crystal silicon and stainless steel samples.
