Enhanced scattering of acoustic waves at interfaces. Zhao, L, Liu, B, Gao, Y H, Zhao, Y J, & Huang, J P Frontiers Of Physics, 7(3):319–323, 2012. ISBN: 2095-0462![Enhanced scattering of acoustic waves at interfaces [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex We propose a general method to realize a total scattering of an incident acoustic wave at interfaces between different media while allowing the flow of air, fluids and/or particles. This originates from the enlargement of the equivalent acoustic scattering cross section of an embedded object coated with acoustic metamaterials, which causes the coated object to behave as a scatterer bigger than its physical size. We theoretically design a model circular cylindrical object coated with such metamaterials whose properties are determined according to two different, but identical, methods. The desired function is confirmed for both far-field and near-field cases with full wave simulations based on the finite element method. This work reveals a promising way to achieve noise shielding and naval camouflage.
