Abstract
Presents a self-contained theoretical study of wave tunnelling in underwater acoustics. After a brief review of tunnelling in quantum mechanics and of the basic wave theory in underwater acoustics, deals with the two major topics of this report: (a) the leakage of the acoustic wave field from the surface duct into the lower half space, and (b) wave propagation in a double-duct system. Proposes physically reasonable and analytically solvable models and discusses the theoretical formalism for studying each of these two processes. A brief annotated bibliography is included.
