On the reflection of time-domain acoustic spherical waves by a sinusoidal diffraction grating

Gao Guochao Cristini Paul Favretto-Cristini Nathalie Deumié Carole

Abstrak

This work reports on some results obtained from numerical simulations of time-domain acoustic wave propagation in the presence of a periodically rough interface. Emphasis is put on the structure of the reflected signals in the presence of a sinusoidal grating. More specifically, we investigate the effect of the frequency bandwidth of the emitted signal and the effect of the incident wavefront sphericity on the signals reflected from the rough interface and associated with the different diffraction orders.
