Simons, D.G. TNO Fysisch en Elektronisch Laboratorium Publication year 2004 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 Subject PhysicsUnderwater acousticsComputational methodsNumerical analysisPressure effectsSedimentsCaustic envelopesPower lawsSound pressureSound transmission To reference this document use: http://resolver.tudelft.nl/uuid:c833a204-8b21-4317-b04f-922b79304f3e DOI https://doi.org/10.1121/1.1650841 TNO identifier 215314 Source Journal of the Acoustical Society of America, 115 (4), 1449-1459 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
