In this work, we present theoretical analyses of the acoustic radiation force acting on non-spherical particles, as well as experimental demonstration of particle trapping assisted by the artificially engineered acoustic field of the phononic crystal plate. The capsule-shaped particles, a kind of common non-spherical-shaped particles, in practical cases, are chosen as study objects. The dependence of the acoustic radiation force on different parameters such as the frequency, position, and orientation of a capsule-shaped particle is evaluated, and the analysis shows the orientation angle also has a great influence, which is quite different from the spherical particles. Due to the extraordinary resonant transmission of the phononic crystal plate, the periodically distributed acoustic field is obtained to realize trapping on capsule-shaped particle(s). This method could be envisaged to pave a way of delivering drugs or cells and small fibers in biology and medicine.
