Abstract: Abstract A novel approach for numerically propagating acoustic waves in two-dimensional quiescent media has been developed through a fully convolutional multi-scale neural network following a spatio-temporal auto-regressive strategy. This data-driven method managed to produce accurate… read more here.

DOI: 10.1121/1.5014322
Abstract: Thermoviscous dissipation plays an important role in sound propagation through acoustic metastructures for a variety of applications. The thermoviscous effects rely on the resonances in the structures of subwavelength features. Our analyses and numerical simulations… read more here.
