Description:
Author(s): Weitao Yuan, Jinfeng Zhao, Bernard Bonello, Bahram Djafari-Rouhani, Xiaoqing Zhang, Yongdong Pan, and Zheng Zhong Wave guiding is important in acoustic circuits for on-chip devices that are essential for several fields, including telecommunication, sensing, and medical imaging. Designing configurable guiding devices is still in its early stages, however. The authors construct acoustic guides by adding a line of hollow pillars to a forest of solid pillars on a thin plate, and demonstrate evidence of guiding due to the whispering-gallery mode. They also show interesting phenomena, such as the evolution of the guided beam pattern and asymmetric transmission of plate waves. These results should promote the design of more sophisticated waveguides and acoustic circuits. [Phys. Rev. Applied 10, 034010] Published Thu Sep 06, 2018
