Graded negative index lens with designable focal length by phononic crystal
Ke Deng, Yiqun Ding, Zhaojian He +3
We realize a flat lens with graded negative refractive index by a two-dimensional phononic crystal. The index-grade is achieved by gradual modification of the filling fraction alon…

Theoretical study of subwavelength imaging by acoustic metamaterial slabs
Ke Deng, Yiqun Ding, Zhaojian He +3
We investigate theoretically subwavelength imaging by acoustic metamaterial slabs immersed in the liquid matrix. A near-field subwavelength image formed by evanescent waves is achi…

Extremal transmission and beating effect of acoustic wave in two-dimensional sonic crystal
Xiangdong Zhang, Zhengyou Liu
The extremal transmission of acoustic wave near the Dirac point in two-dimensional (2D) sonic crystal (SC), being inversely proportional to the thickness of sample, has been demons…
