概要

• 論文の詳細を見る

• A relationship between normal modes and rays in the underwater sound field is investigated numerically. Acoustic energy flow along ray path is supplied by the interference of neighboring modes. At low frequencies surface or bottom interaction cause disagreement between mode interference cycle distance and classical ray cycle distance. If the number of summed modes decreases, the energy flow becomes fuzzy and the sound field shows the feature of individual mode.
