Inverse design of reconfigurable piezoelectric topological phononic plates
Chuong Nguyen, S. S. Nanthakumar, Xiaoying Zhuang +3
We present a methodology to perform inverse analysis on reconfigurable topological insulators for flexural waves in plate-like structures. First the unit cell topology of a phononi…
Gradient index phononic crystals and metamaterials
Yabin Jin, Bahram Djafari-Rouhani, Daniel Torrent
Phononic crystals and acoustic metamaterials are periodic structures whose effective properties can be tailored at will to achieve extreme control on wave propagation. Their refrac…
Engineered diffraction gratings for acoustic cloaking
Yabin Jin, Xinsheng Fang, Yong Li +1
We show that engineered diffraction gratings can considerably simplify the design and performance of acoustic devices. Acoustic reflecting gratings based on rectangular cavities dr…
Analysis of the Robustness of Conventional and Topologically Protected Edge States in Phononic Crystal Plates
Yabin Jin, Daniel Torrent, Bahram Djafari-Rouhani
In this work we theoretically study the interface acoustic states of resonators on a thin plate with topologically protected and conventional designs. Topologically protected inter…
Gradient Index Devices for the Simultaneous Focusing of the S0 and A0 Lamb Modes
Yabin Jin, Daniel Torrent, Yan Pennec +2
Gradient index devices for the simultaneous control of the S 0 and A 0 Lamb modes are presented and numerically analysed. It is found a special relationship between the refractive…
