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…
Vectorial Acoustic Multiplexed Holography
Yuan Tian, Hao Ge, Jiangpo Zheng +3
Encoding more information into wave fields is a central goal in imaging, communication, and wave control. Optical holography benefits from polarization multiplexing, but acoustic h…
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)…
Boundary-induced helical bulk acoustic transport in LiNbO3 thin films
Zhe Li, Zhen-Hui Qin, Shu-Mao Wu +10
We experimentally demonstrate boundary-induced helical bulk states (BI-HBSs) for RF acoustic transport in LiNbO3 thin-film phononic crystals (approximately 175-200 MHz). A boundary…
K-band LiNbO3 A3 Lamb-wave Resonators with Sub-wavelength Through-holes
Shu-Mao Wu, Hao Yan, Chen-Bei Hao +3
Addressing critical challenges in Lamb wave resonators, this paper presents the first validation of resonators incorporating sub-wavelength through-holes. Using the A3 mode resonat…
