- W2000476061 abstract "Time reversal has successfully demonstrated the ability to focus acoustic waves in the laboratory for several years. However, the minimal focal spot dimension is always larger than half the wavelength, which is in agreement with diffraction limit. We will show that this behavior is related to the presence of a diverging wave that is always created after the convergent wave collapse at the focus. In a time reversal experiment, by replacing the initial source by its time reversed image, we may eliminate this diverging wave. Such a process allows to create an acoustic sink which absorbs the converging wave. Thus, with the elimination of the diverging wave, the focal spot can become much smaller than the one predicted by the diffraction limit. In this paper, we present the first experimental demonstration of an acoustic sink and we observe focal spot smaller than 1/14 the wavelength." @default.
