Gradient index sonic lenses based on two-dimensional sonic crystals are here designed, fabricated, and characterized. The index-gradient is achieved in these type of flat lenses by a gradual modification of the sonic crystal ...
We propose and numerically demonstrate the feasibility of spatial filtering, i.e. a selective removal of the high spatial frequency components, of narrow acoustic beams during their propagation along a two- dimensional ...
