Abstract: | Summary Dispersion in Rayleigh waves is discussed for semi-infinite media with =
1(1 ± cos s z) and =
1(1 ± cosh s z), being the rigidity of the medium. A few workers tried with the above Fourier type of model but failed to find the dispersive nature. Because they neglected s due to the complexity of the calculation they arrived at a non dispersive frequency equation. This difficulty is removed in this paper and a dispersive frequency equation is obtained which shows both direct and inverse dispersion. The second model leads to non-convergent solution forz![rarr](/content/g542r74305837847/xxlarge8594.gif) but shows many interesting results which are also discussed. |
