透射型声超表面斗篷的设计
Design of Ultrathin Transmissive Acoustic Cloak
摘要
Abstract
Acoustically transmissive cloak is constructed with a combination of two labyrinthine type metasurfaces-phase-modulated metasurface and near-zero refractive index metasurface.The near-zero re-fractive index metasurface is verified by energy band calculation and equivalent medium theory to have zero refractive index property similar to phonon crystals,so that it can guide the acoustic waves to contin-ue to go around the obstacles in the original direction of the acoustic waves;the phase-modulated meta-surface,on the other hand,should have a high transmittance while having the role of phase-modulation to ensure that the acoustic waves can pass through in large quantities.The simulations and calculations show that the acoustic transmission cloak formed by the construction works well.关键词
