Acoustic propagation from a spiral wave front source in an ocean environment
BT Hefner, BR Dzikowicz - The Journal of the Acoustical Society of …, 2012 - pubs.aip.org
A spiral wave front source generates a pressure field that has a phase that depends linearly
on the azimuthal angle at which it is measured. This differs from a point source that has a …
