Retrievial of a Time-Dependent Source in an Acoustic Propagation Problem

Résumé

Consider two media separated by a plane interface, a time- dependent source F(t) at a point S in the first medium (of the lower celerity), receivers in the second medium, located at a large radial distance from the source. Thanks to a diffusion-like behaviour of the transmitted wave, we are able to retrieve the term F(t), under high frequencies hypothesis in an elementary way.
