Radiation pressure in three-dimenyional acoustic media, described by one-dimentional Helmholtz equation

Calculation of the average pressure caused by normally falling progressive plane wave at its dispersion on the laminated inclusion of the final thickness between two homogeneous liquid semispaces with different properties is discussed. Properties of dispersion matrix elements of the resulting one-dimensional problem in terms of reflection and refraction factors are presented. The physical significance of correlation between dispersion matrix elements is analyzed.
