Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The ocean is transparent to sound where slight irregularities within the ocean cause sound fluctuations, and thus set limits on the many uses of sound in the ocean, similar to the limits imposed by the atmosphere on ground-based telescopes. This 1979 book attempts to connect the known structure of the ocean volume with experimental results in long-range sound transmission. Theories of wave propagation through irregular media, developed for optical and radio wave transmission are found to be inapplicable in many respects due to the complications of ocean structure, particularly the combination of anisotropy and 'sound channel'. The authors extend wave propagation theory to account for the ocean complications and introduces the path-integral approach to the solution of the strong-scattering regime that solves many long-standing problems. The book is written at the post-graduate level, but has been carefully organised to give experimenters a grasp of important results without undue mathematics.

Presumed first edition/first printing. [2], 112 p. Includes illustrations. Velobound. References. Roger Frederick Dashen (May 5, 1938 in Grand Junction, Colorado-May 25, 1995 in La Jolla) was an American theoretical physicist who studied particle physics and quantum field theory. Dashen studied physics at the Harvard University then he went to Caltech, where he earned his PhD in 1964. After that, he was a professor at Caltech in 1967 and the Institute for Advanced Study in 1969. In 1986 he became a professor at the University of California, San Diego (UCSD) in 1988 was Head of Faculty. He played a leading role in the establishment of a supercomputer center at UCSD and in the establishment of the Institute for Theoretical Physics of the National Science Foundation at the University of California, Santa Barbara. He helped develop the Dashen-Hasslacher-Neveu method (DHN) for quantization of solitons using path integrals. Dashen was also involved in sound propagation in the ocean (with military applications in mind), where he applied quantum field theoretical methods (such as path integrals and the renormalization group) on the problem of random scattering of sound in the ocean. He worked with his JASON colleagues Kenneth Watson and Frederik Zachariason. He was a member of the JASON Defense Advisory Group. Good. No dust jacket. Cover has some wear and soiling.
