Wave localization as a manifestation of ray chaos in underwater acoustics

A. Iomin, Yu. Bliokh

摘要:

通过研究波在周期性波纹波导中的传播,证明了波的混沌性。在短波近似(SWA)的限制下,基本的描述与混沌射线动力学有关。在这种情况下,该问题的控制参数的特点是由振幅和SWA参数。所考虑的模型是相当合适的和易处理的波局部化长度的分析。本征模的数目表征的局部波包的宽度估计解析。

英文摘要:

Wave chaos is demonstrated by studying a wave propagation in a periodically corrugated wave-guide. In the limit of a short wave approximation (SWA) the underlying description is related to the chaotic ray dynamics. In this case the control parameter of the problem is characterized by the corrugation amplitude and the SWA parameter. The considered model is fairly suitable and tractable for the analytical analysis of a wave localization length. The number of eigenmodes characterized the width of the localized wave packet is estimated analytically.
