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

Slinky-whistler dispersion relation from 'scaling'.
Although the number of the data is limited, we are able to say that the linear dispersion relation can be used ordinarily for the ocean waves except for the special cases where very steep waves are generated by extremely strong wind.
Dispersion relations have been obtained separately in the cases of electrical open circuit and short circuit.
In particular, the exact dispersion relation of the plasma column loaded cylindrical waveguide was presented in different forms with different notations in [15, 48, 51, 52].
The incident wave and the reflection wave exist simultaneously, and their corresponding induced currents on the tape helix also exist simultaneously to satisfy the boundary conditions and the dispersion relation of the helical transmission line.
ANALYTICAL AND NUMERICAL INVESTIGATION OF DISPERSION RELATION FOR AN INFINITE PERIODIC STRUCTURE
The dispersion relation in (2) can be used to show that the new loaded transmission line exhibits an effective larger electrical length compared to a conventional transmission line having the same physical length at frequencies below the S-SRR's resonant frequency.
In addition from the dispersion relation is possible obtain relevant information of the plasma such as the temperature and the density.
The desired dispersion relation of this circuit model can be obtained through standard periodic analySiS based upon the 1-D) symmetric unit cell in Fig.
