Topology optimization of acoustic metamaterials with negative mass density using a level set-based method

Topology optimization of acoustic metamaterials with negative mass density using a level set-based method

Much effort has been made to experimentally fabricate acoustic metamaterials that display novel properties, such as single or double negativity, negative refractive index. The novel properties displayed by acoustic metamaterials and their deep subwavelength nature, whereas the size of phononic cryst...
