Lastovenko O. Scalar and vector fields in the horizontal-stratified waveguides of the shallow water

Dissertation is dedicated to the simulating the scalar fields of acoustic pressure and the vector fields of particle velocity and intensity flow. In work the original method of simulating of vector fields in wave guides with is horizontal-layered structure is developed. The field of a intensity flow its calculated "by definition", as a product of pressure field and a components of a particle velocity field. The field of pressure and field of particle velocity is represented as the sum of normal modes. The fields of normal modes of particle velocity are calculated on the basis of differential relations between particle velocity and acoustic pressure. At such approach for some models of wave guides the field of a normal mode of particle velocity it is possible to receive in an analytical view. Within the limits of the developed method vertical structures of normal modes of pressure and a component of particle velocity are calculated.
