Abstract Acoustic wave propagation has been the subject of many studies in engineering and physics. Researchers
have shown an increased interest in recent years in the acoustic scattering of periodic systems, such as
phononic crystals and metamaterials [1]. These artificial periodic systems possess some particular acoustic
characteristics including noise control, waveguides and negative refraction, which manifest excellent
potential applicability in acoustic engineering. Based on the isogeometric acoustic boundary element
method (BEM) [2], an efficient shape optimization approach is proposed in this research for threedimensional doubly-periodic multi-layered systems. The interfaces between different acoustic mediums are
infinite doubly… More >
