Conditions for forming weakly diverging acoustic bundles in ocean waveguides

Necessary and sufficient conditions for the dependence of the cycle length of the Brilloin waves or rays of geometrical acoustics on the ray parameter that is inversely proportional to their phase velocity are formulated. The formulated conditions determine the existence of weakly diverging acoustic...

Description
Summary:Necessary and sufficient conditions for the dependence of the cycle length of the Brilloin waves or rays of geometrical acoustics on the ray parameter that is inversely proportional to their phase velocity are formulated. The formulated conditions determine the existence of weakly diverging acoustic bundles in vertically stratified oceanic waveguides, even with a point sound source.
