ajst-6289	Cao, Yafei; Yao, Yuanwei; Feng, Huiping	Schoch Effect in Topological Phononic Crystals	2023	6	.pdf	application/pdf	3947	176	48	In 2004, Declercq et al. extended the theory of non-uniform wave diffraction to acoustic diffraction with negative Schoch displacement In order to further investigate the Schoch effect in acoustics, based on the research methods and experimental conclusions of optical metamaterials in [17], this paper designs a model that effectively achieves negative Schoch displacement in near-zero refractive index acoustic metamaterials with different physical characteristics by controlling the scattering body rotation direction and the thickness of the covering layer water at different parameters.	cache/ajst-6289.pdf	txt/ajst-6289.txt
