| Abstract: | Summary The numerical properties of the low-frequency expansions for the reflection and transmission coefficients of SH-waves from transition layers, derived in 1], are studied. It is shown that the expansions are suitable for computations only when the thickness d of the transition layer is small in comparison with the wavelength  of the incident wave (d 0.5). For thicker transition layers, certain modifications of the method are suggested. |
