Short-Wave Diffraction on Bodies with an Arbitrary Smooth Surface

摘要

The classical problem of the scattering of a high-frequency acoustic wave emitted by a point source is analyzed. The scattering occurs on an arbitrary smooth surface S of an obstacle. Below, we consider the time dependence of pressure to be monochromatic, i.e., p(x,y,z,t) = Re[p(x,y,z)exp-(-iωt)], and the boundary S of the obstacle to be acoustically solid: partial derivp/partial derivn|s = 0
