Acoustic planar hyperlens via transformation acoustics

摘要

An acoustic planar hyperlens is designed using transformation acoustics. Magnification effects are added to a planar channelling lens to obtain the planar hyperlens. A layered system approach is employed to achieve an effective transformation medium. The proposed planar hyperlens is capable of magnifying sub-diffraction-limit objects on one flat surface and forming magnified images which are above the diffraction limit on another flat surface.
