The reflection, refraction, and absorption of obliquely incident plane harmonic antiplane strain (SH) waves at a frictional interface between dissimilar semi-infinite elastic solids is investigated by an approximate analytical approach. The frictional stress at the interface is assumed to depend on the...
(11.2) $$ The assumption of a lossless medium, however, is an idealization. There is always some loss of acoustic energy when sound propagates in real media. This is the so-called dissipation of sound energy into thermal energy. Dissipation causes spatial damping of the sound waves....
The invention also allows for the adaptation of the refraction inde 在光学道路允许光学 (特征厚度的选择,折射率) 和吸收由反射避免或限制光损失在综合基体中心支持和半导体影片之间。 发明也考虑到折射索引的适应在基体和半导体影片之间。 [translate]

All light behaves the same, regardless of its source. Light travels in a straight line as long as it is moving through the same medium. REFLECTION: The change in direction of a light ray when it bounces off a surface. MEDIUM: The substance through which light travels. RAY: A straight li...
The wave may vary due to reflection from the obstacle, diffraction around the obstacle, and transmission accompanied by a refraction to the obstacle and other space. One part of the soundwave passes through the boundary of space. The second part is reflected. The reflection itself and its ...
当光波照射到某个物体时,可能会被该物体吸收、反射或折射。所有物体都会产生一定程度的反射和吸收。 注意 在自然界中,光也可能会透射过物体。即,光可以毫无影响地通过物体(如 X 射线)。但是,在 Autodesk® Maya® 中不会表示这些类型的光,因为这些光不会产生任何视觉效果。 吸收。 光在物体上停止且...
Effects considered in this context are dissipation during sound propagation in air, dissipation during sound propagation in porous media, reflection, scattering, and the degree of absorption of walls and other absorbent materials. Common means to control absorption are discussed in detail, in particular...
