Successful numerical demonstration of acoustic cloaking.

Implementation of acoustic imaging with complementary media.

Extension of electromagnetic concepts to acoustics.

Abstract

Base on the concept of complementary media, a scheme to achieve cloak an object outside the shell is proposed by Yun lai et al [PRL 102, 093901].We generalize the concept in acoustic waves and demonstrate numerically how to achieve the acoustic cloaking and imaging with complementary media.
