Acoustic wave transmission channel based on phononic crystal line defect state
Source abstract
Abstract
To generate directional transmission characteristics of acoustic waves, we constructed two abnormal transmission models based on the protocell. The simulation results showed that the band gap characteristic of the phononic crystal structure can be used to realize the directional transmission effect. We also found that the acoustic frequency has a great influence on the acoustic transmission characteristics of artificial acoustic structures. Because the artificial acoustic structure based on phononic crystals has the advantages of design flexibility, it can be customized according to the actual engineering application. Our results provided a new direction for engineering applications such as directional transmission of acoustic waves and acoustic diodes.
