Supercell-enabled inverse design of boundary-state dispersion for group-velocity control in pseudomagnetic phononic crystals
Hua-Yang Chen, Nan-Xin Yu, Zhen-Hui Qin +2
Topological boundary states offer a platform for guided-wave propagation within bulk bandgaps. Their propagation characteristics depend not only on the spectral extent of the state…
Complementary-polarity double-layer LiTaO3 resonators for symmetry-selective SH2 excitation with ultrahigh electromechanical coupling (kt^2 = 25.7%)
Hao Yan, Zhen-hui Qin, Zhi-Wen Wang +7
We report a structurally simple double-layer lithium tantalate (LiTaO3) bulk acoustic resonator that enables symmetry-selective excitation of the second-order thickness-shear (SH2)…
Deployable Nanoelectromechanical Bound States in the Continuum Enabled by GHz Lamb Wave Phononic Crystals on LiNbO3 Thin Films
Sheng-Nan Liang, Zhen-Hui Qin, Shu-Mao Wu +3
Bound states in the continuum (BICs) are a fascinating class of eigenstates that trap energy within the continuum, enabling breakthroughs in ultra-low-threshold lasing, high-Q sens…
Double-layer Thin-film LiNbO3 Longitudinally Excited Shear Wave Resonators with Ultra-large Electromechanical Coupling Coefficient and Spurious-Free Performance
Zhen-Hui Qin, Shu-Mao Wu, Chen-Bei Hao +4
This work proposes a double-layer thin-film lithium niobate (LiNbO3) longitudinally excited shear wave resonator with a theoretical electromechanical coupling coefficient exceeding…
