Bifurcations, chaos and control of chaos in spin-wave instabilities

Journal of Magnetism and Magnetic Materials, 1992
Abstract An experimental study of microwave pumped spin-wave instabilities in YIG reveals new types of bifurcations and the possibility of controlling chaos with a small perturbation in a system parameter.

Strange attractors in spin-wave chaos

Physica A: Statistical Mechanics and its Applications, 1990
Abstract Interacting spin-wave modes pumped by microwave radiation in magnetic crystals display a rich variety of nonlinear dynamic effects such as self-oscillations, intermittency, period multiplication bifurcations and chaos. We review recent experiments in this area and present measurements to characterize strange attractors at the onset of chaos ...

Wave Chaos in Elastodynamics

2001
Recent years have demonstrated that ultrasonic waves in solids permit investigations of wave chaos, reverberation and multiple scattering that complement those of microwaves, optics and electronics. The large quality factors that can be achieved with elastic waves, their relatively slow wave speed, and their good impedance mismatch with the laboratory,

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.

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 ...

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 ...

Perturbations, chaos, and waves /

2001
Thesis (PhD)--University of South Australia, 2001. Includes bibliographical references (pages 225-232) In this dissertation, partial differential equations are derived which model the effect of sinusoidal, vertical forcing upon the surface of an infinitely deep, incompressible and quasi-irrotational (weakly vortical) fluid confined between two vertical

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 ...
