On the nonspecular reflection of bounded acoustic beams

In this article, a comprehensive study of the reflection phenomenon of bounded acoustic beams by uniform and layered half-spaces and plates is carried out. The incident beam strength is assumed to have a Gaussian variation with different widths and frequencies. The Thomson–Haskell matrix method with delta matrix modification is adopted to solve this problem. Different types of reflectors only change the boundary and continuity conditions but the basic formulation remains unchanged. Several interesting and new features of reflected beam profiles are observed.
