Acoustic Focusing Imaging Characteristics Based on Double Negative Locally Resonant Phononic Crystal
To achieve high-efficiency and high-resolution acoustic focusing, we used artificial periodic acoustic structures composed of cell arrays to manipulate the acoustic transmission wave front, and used finite element software to simulate the acoustic field characteristics. We found that when focuses ge...
