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…
