The Self-Focusing Effect of Nondirected Acoustic Emission in Layered Media

摘要

If an acoustic field from a nondirected pointed source is located in a layered medium, for example, in an aquatic medium, and a half-infinite space with a bottom, we apply one physical model of the medium or another. Most frequently, the Pekeris waveguide model is used. Two principally different model approaches are possible to solve the boundary problem: the self-conjugate approach (classic) described in [1-3] and the non-self-conjugate approach (general) described in [4].
