Lecture: Guiding acoustic waves over obstacles using linear surface modes

Author(s): Farooqui Maaz, Aurégan Yves, Pagneux Vincent

A reflection-less acoustic cloak inside ducts is proposed in the audible range where plane waves are bended around the object using boundary impedance. The cloak possesses low-reflection and wave-front bending properties, which\ncould approximate the ideal cloak with inhomogeneous and anisotropic distribution of material parameters. The cloak is effective in a broadband frequency range, and the cloaking range is a function of the boundary impedance.
