| 21. | The dispersion relation for these waves is:
|
| 22. | Their dispersion relation reads, for waves on the interface between two fluids of infinite depth:
|
| 23. | In order to obtain the dispersion relation it is possible to proceed in two different ways.
|
| 24. | The dispersion relation for extraordinary waves is
|
| 25. | The group velocity therefore depends upon the dispersion relation connecting ? and " k ".
|
| 26. | Each of these components travels with its own phase velocity, in accordance with the dispersion relation.
|
| 27. | The underlying reason for the difference in dispersion relation is that ferromagnets violate time-reversal symmetry.
|
| 28. | The parameter describes the frequency dependence of the sound velocity of the membrane ( dispersion relation ).
|
| 29. | The frequency ? as a function of "'k "'is the dispersion relation.
|
| 30. | The polarization dependent phase shift is also the reason why TE and TM guided modes have different dispersion relations.
