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

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

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 e...
