By combining purpose-built materials and neural networks, researchers at EPFL have shown that sound can be used in high-resolution imagery.Imaging allows us to depict an object through far-field analysis of the light- and sound-waves that it transmits or radiates. The shorter the wave, the higher the image’s resolution. However, the level of detail is limited by the size of the wavelength in question – until now. Researchers at EPFL’s Laboratory of Wave Engineering have successfully proven that …
