Spherical wave reflection at impedance interface of two mediums
Engineering Education # 03, March 2011 The new solution of the problem of the directed sound beams reflection at the interface between liquid half-space and solid half-space is analyzed. This solution is received in a class of the generalized functions, which are the conjugate solutions of the appropriate not self-conjugate boundary problem. It is marked, that reflectance of spherical components of the total solution in the field of angles of complete internal reflection is less than one. The reflectance takes the minimal value when falling angle corresponds to generation of Rayleigh wave. The analytical expression for shift of the directed sound beams is received for reflection, which angular dependence precisely corresponds to observed dependence in classical Schoch experiments.
