Description
Summary:A generalization of the modified Cagniard method ('Cagniard-DeHoop method') is used to obtain closed-form analytic time-domain expressions for the line-source excited pulsed acoustic wave pressure associated with the reflection against the mass-loaded planar boundary of a semi-infinite fluid. The expressions reveal the generation of anomalous waveforms near the boundary at large offsets from the source. Their occurrence can be interpreted as a surface effect. As the analysis shows, they are, however, not surface waves in the strict sense of the definition.
