摘要
Three-component phononic crystals line-defects composed of aluminum, rubber and water were introduced to the aluminum pillars arrayed in water for controlling of the acoustic beam. The propagation properties of self-collimation-based acoustic waves were investigated by finite element method in the designed PC structure. Results reveal that the line-defects can lead to two splitting wave beams. The beam splitter PC structure can be controlled by adjusting the radii of the rods and the coating layer in the line defects. When the acoustic speed of the coating layer changes, the splitting propagation of the acoustic wave can be changed. The output acoustic wave can be altered by controlling the phase difference of the two incident sound sources. (C) 2019 Elsevier Ltd. All rights reserved.
