Wave Chaos and Chaotic Transmission of Waves

1997
Abstract : Our goal is to develop an analytical and numerical approach to diagnose arrival sound waves from long-distanced sources on the basis of the most advanced methods of dynamics that include ray dynamics, wave dynamics reconstruction on the basis of ray dynamics, specific asymptotic solutions in the short-wave approximation, and specific ...

Spatiotemporal Chaos in Interfacial Waves

1991
Spatiotemporal chaos occurs in many hydrodynamic systems. This state is distinguished from temporal chaos by at least partial loss of coherence between different spatial regions, and from fully developed turbulence by the absence of a cascade. Several experimental and theoretical examples of spatiotemporal chaos are briefly reviewed.

Intrinsic chaos in a plasma wave

Physics of Fluids B: Plasma Physics, 1990
The linear plasma response to an electrostatic wave is described by the Van Kampen–Case–Siewert (VCS) modal structure using Lie transform techniques. The VCS structure, which is well known to give rise to Landau damping, is also proved to be responsible for chaotic particle response and diffusion in phase space in the quasilinear limit.

Controlling spin-wave chaos

Journal of Applied Physics, 1994
Microwave pumped spin-wave instabilities in YIG spheres were one of the first experimental systems used to demonstrate that chaos can be suppressed by small periodic modulations in an accessible system parameter. Here we show that the equations describing two interacting spin-wave modes account satisfactorily for the experimental results, as long as ...

Wave-particle chaos in the magnetosphere

Physica D: Nonlinear Phenomena, 1994
Abstract The nonlinear interaction between the bounced motion of a proton and the kinetic Alfven wave excited in the magnetosphere is studied. Using the Poincare surface of section technique, the motion of the proton is traced numerically in phase space.

Nonlinear Waves, Solitons and Chaos

2000
This revised and updated second edition of a highly successful book is the only text at this level to embrace a universal approach to three major developments in classical physics; namely nonlinear waves, solitons and chaos. The authors now include new material on biology and laser theory, and go on to discuss important recent developments such as ...

The Long Waves: Evolution or Chaos?

1995
An intriguing aspect of the advance of knowledge in theoretical physics is the link between microcosmos — the atom and its constituents — and macro-cosmos — the nebulosae, distant Milky Ways, and black holes. Apparently, knowledge about elementary particles such as protons and bosons and muons can be directly translated into knowledge about the “big ...

Chaos and wave propagation regimes

The Journal of the Acoustical Society of America, 2003
Ray chaos theory and parabolic equation numerical modeling were two thrusts of Fred Tappert’s research that were perpetually in tension. Fred was interested in the problem of identifying wave propagation regimes, most notably the strong focusing caustic regime and its evolution into the saturation regime.
