WebJun 15, 2024 · The existence of antichiral edge states is revealed through full-wave simulations of the band structure and acoustic fields excited by a point source. Furthermore, we compare these antichiral edge states with conventional chiral edge states. It is found that the antichiral edge states are less robust than the chiral ones. WebApr 13, 2024 · The propagation process of the free wave in the infinite chiral S-shaped media is studied through employing the FE simulation and Bloch’s theorem. By applying the standard FE program, the eigenvalue equations used to depict wave propagation process can be presented as: ... Tunable acoustic wave propagation through planar auxetic …
