On-Chip Shaping of Surface Acoustic Waves via Continuous Diffractive Modulation

Precise shaping of surface acoustic waves (SAWs) on anisotropic piezoelectric substrates is complicated by elastic anisotropy and electromechanical coupling. Here we introduce a continuous diffractive acoustic lens (CDAL), in which weak phase-velocity perturbations produced by subwavelength metallization, together with...

Acousto-dielectrophoretic enhancement enables label-free ternary separation of submicrometer particles

Label-free separation of multiple micrometer and submicrometer particle populations from complex samples is a critical but elusive capability. We report an integrated acousto-dielectric chip in which the piezoelectric potential associated with tilted-angle standing surface acoustic waves changes the local electric fiel...
