内容記述 | To ascertain and supplement previous results obtained in the case of a P wave incident upon a corrugated interface, the case of incidence of an SV wave and the phase change upon reflection and refraction were considered. In the case of normal incidence of an SV wave, computation for three models and in the case of oblique incidence of an SV wave that for angles of incidence smaller than 16° for one model were made. Although these results support those for the case of an incident P wave, there are several new features. For example, it is not always valid for large angles of incidence that the effect of corrugation is larger on reflection than on refraction, since the amplitude of regularly reflected S waves is affected by the angle of incidence. Phase changes upon reflection and refraction are not large for regular waves. The velocity contrast between media concerned seems to play an important role for phase changes. For irregular waves there are large phase changes, but it is considered that the contribution to the amplitude of waves is not large since irregular waves travel in different directions to each other. | |||||
