Abstract
A compilation of analytical formulas is presented, describing ray properties of a family of sediment sound speed profiles. The profiles are described as "generalized power law" profiles because they are generalizations of a similar family of simpler power law profiles considered in earlier work [M. A. Ainslie, J. Acoust. Soc. Am. 96, 2506–2515 (1994)]. Properties considered include ray paths, caustic envelopes, and cusp coordinates due to a point source in isovelocity water. For a few example cases the caustic shapes are illustrated by computing the pressure field using a normal mode program. © 2004 Acoustical Society of America
