Transmission acoustique a travers le dioptre air-eau
Résumé
This paper presents a problem of acoustic transmission through the air-water interface, in the case of a spherical harmonic point-source. From the resolution of the integral, formulation of the Helmholtz equation, we show in the case of a plane interface (low sea state) separating two homogeneous and isotropic media, interferences between direct refracted waves and inhomogeneous waves that cannot be obtained by means of the geometrical optics. Numerical simulations of the interferences field will be presented, in the same way as the contribution of these waves, considered separately.
