Interpreting wave phenomena in terms of an underlying ray dynamics adds a new
dimension to the analysis of linear wave equations. Forming explicit connections between …

Underwater acoustic channels are band-limited and reverberant, posing many obstacles to
reliable, phase-coherent acoustic communications. While many high frequency …

▪ Abstract We review the use of ray models for internal waves, particularly formulations for
calculating wave amplitudes along the ray. These are expressed in spatial, wave number …

Tsunamis exhibit surprisingly strong height fluctuations. An in-depth understanding of the
mechanisms that lead to these variations in wave height is a prerequisite for reliable tsunami …

Context. The asteroseismology of rapidly rotating pulsating stars is hindered by our poor
knowledge of the effect of the rotation on the oscillation properties. Aims. Here we present …

Based on the method of canonical transformation of variables and the classical perturbation
theory, this innovative book treats the systematic theory of symplectic mappings for …

A ray-based wave-field description is employed in the interpretation of broadband basin-
scale acoustic propagation measurements obtained during the Acoustic Thermometry of …

Ports are gateways for aquatic invasions. New arrivals from maritime traffic and disturbed
environmental conditions can promote the settlement of exotic species. Molluscs fall into the …

A systematic study of chaotic ray dynamics in underwater acoustic waveguides began in the
mid-1990s when it was realized that this factor plays a crucial role in long-range sound …

The effects of rapid stellar rotation on acoustic oscillation modes are poorly understood. We
study the dynamics of acoustic rays in rotating polytropic stars and show using quantum …
