15-7 Reflection and Transmission. Lecture 08 - Reflection and transmission of waves.ppt - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. 3.2 Reflection/transmission - oblique incidence A more general situation of reflection and transmission of waves at an interface occurs when the incident wave strikes at an oblique angle. The reflection loss during acoustic wave scattering from solid boundaries at the ocean bottom was calculated by Kuo (1992). first solutions for the problem of reflection and transmission of plane waves by a dielectric half-space in vacuum moving parallel and perpendicular to the interface was solved [3], [4]. (a) The end of the cord is fixed to a peg. Param eters of bubbly liquid are the same as on figure 2, curves 1 – α 20 =0.0025, curves 2 – α 20 =0.005, curves 3 – α 20 =0.01.

The mode conversions during the reflection and transmission of seismic waves at the boundaries of porous media were studied by de la Cruz et al. Reflection of a wave pulse on a cord lying on a table. density, P-wave velocity and S-wave velocity in a solid medium. Nikolova 2012 LECTURE 05: PLANE WAVE REFLECTION AND TRANSMISSION 8 Reflection and Transmission (Fresnel) Coefficients (Review) • by definition the reflection coefficient Γgives the ratio of the reflected to incident tangential E-field component at the interface • the ratio of the reflected to incident tangential H-field component at the interface is −Γ 1 Incidence, reflection and transmission waves at the fluid–solid interface. (1992). The work by Huang [5] discussed the problem of reflection and transmission of electromagnetic waves when the dielectric is moving in any arbitrary direction. wave transmission and reflection is illustrated. Considering that there is no S-wave in the upper layer, we assume that three possible incident waves are Fig.
