In progress

The concentration of waves below the diffraction limit through sub-wavelength structures is an important advance for high resolution imaging. However, despite the extraordinary transmission potential for the concentration of wave energy, its potential for sub-wavelength imaging has never been shown. A system capable of generating an image by capturing waves on this principle could allow the visualization of the details of an object at a sub-wavelength scale. The BEAT project proposes to develop an acoustic metamaterial device at MHz frequencies for sub-wavelength and broadband focusing of volume waves in solids. Using an experimental approach combined with numerical simulations, the objective is to develop a demonstrator that can reduce the focal point below the diffraction limit and adapt to commercial piezoelectric transducers.
