The evaluation of these expressions was carried out numerically. In the model with the upper layer we can expect two types of trapped waves along the free surface and the interface. One is the well-known Rayleigh waves which exponentially decrease in amplitude toward the inside of the medium. The other is the waves which have trigonometric components in the inside of the lower medium. The second type of waves is named as leaky mode. The waves of leaky mode, though very unstable, have strong effects on the partition of the energy in the scattering problem con- sidered here. In the problems of the surface waves along the plane free surface the study of the leaky mode of the waves has been omitted so far, because it readily disappears due to the unstableness of the waves. However, in the problems along the irregular surface the importance of this type of waves arise. In general, occurrences of the resonant standing P and S waves of leaky mode cause the depression of the transmissibility of the energy of the transmitted waves and, as a reciprocal effect, cause an increase of the energy of the scattered body waves, particularly the S waves. Even in the model with the upper layer (this study) we can expect the same behavior of the energy of the transmitted Rayleigh waves as that in the case without the upper layer (studied before). That is to say, (a) the occurrences of the resonant standing S and P waves in the mountain results in an abrupt decrease of the transmissibility of the transmitted Rayleigh waves through the mountain, and (b) on the contary, the standing Rayleigh waves along the curved surface causes the inverse result, i.e., the higher transmissibility of the transmitted Rayleigh waves.",
