• openAccess   Engineered Diffraction Gratings for Acoustic Cloaking 

      Jin, Yabin; Fang, Xinsheng; Li, Yong; Torrent, Daniel American Physical Society (2019)
      We show that engineered diffraction gratings can considerably simplify the design of acoustic ground cloaking devices. Acoustic reflecting gratings are designed in such a way that all the incident energy is channeled ...
