Elastic metamaterial with simultaneously negative Mass Density, Bulk Modulus and Shear Modulus
Ji-En Wu, Xiaoyun Wang, Bing Tang +3
We present a study of elastic metamaterial that possesses multiple local resonances. We demonstrated that the elastic metamaterial can have simultaneously three negative effective…
Acoustic one-way mode conversion and transmission by sonic crystal waveguides
Shiliang Ouyang, Hailong He, Zhaojian He +2
We proposed a scheme to achieve one-way acoustic propagation and even odd mode switching in two mutually perpendicular sonic crystal waveguides connected by a resonant cavity. The…
Splitting of self-collimated beams in two-dimensional sonic crystals
Bo Li, Jun-Jun Guan, Ke Deng +1
An easy-to-implement scheme to split self-collimated acoustic beams in sonic crystals (SCs) is proposed by introducing line-defects into SCs, by which an incoming self-collimated b…
Acoustic guiding and subwavelength imaging with sharp bending by sonic crystal
Bo Li, Ke Deng, Heping Zhao
A sharp bending scheme for the self-collimation of acoustic waves is proposed by simply truncating the sonic crystals. An all-angle and wide-band 90°-bending wave guide is demonstr…
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…
