Robust acoustic cloaking with density-near-zero materials
Jiajun Zhao, Tiancheng Han, Zhining Chen +2
Using the phenomenon of extraordinary sound transmission (EST) through artificially constructed density-near-zero (DNZ) materials, we propose an alternative approach to realize a v…

Acoustic Wavefront Manipulation: Impedance Inhomogeneity and Extraordinary Reflection
Jiajun Zhao, Cheng-Wei Qiu, Zhining Chen +1
Optical wavefront can be manipulated by interfering elementary beams with phase inhomogeneity. Therefore a surface allowing huge, abrupt and position-variant phase change would ena…
