Broadband Reflective Elastic Mode Conversion Enabled by a Single Row of Inclined Long-Slits
Kaifei Feng, Weidong Wang, Yucheng Gao +4
Broadband longitudinal-to-transverse mode conversion under normal incidence remains difficult to achieve, especially with structurally simple designs. Numerical simulations show th…

Lines of Bound States in the Continuum in a Phononic Crystal Slab
Lin Yang, Riyi Zheng, Sheng Zhang +7
We demonstrate that bound states in the continuum (BICs) form continuous lines along high-symmetry directions of momentum space in a simple phononic crystal slab. Contrary to commo…
