Method: Hybrid mode-flux theory
Model output: propagation loss in the water layer
Description: Coupled normal mode theory can be used to model the propagation in the range dependent media. Our coupled-mode approach is based on fluid and elastic seabed options. Based on the continuity and orthonormality conditions, the acoustic wavefield can be modeled in the range-dependent media. The normal mode eigenvalues are calculated by SILENCE root finder algorithm. As an application of this model, the propagation characteristics can be calculated accurately when a single or multiple bubble curtains are present. The geometrical shape of the bubble curtains can also be considered. The model can be combined for the different source types.
