Abstract
In this work, we studied one-dimensional phononic structures for selective acoustic filtering. The structures are composed of three and four materials which have different elastic properties. We have observed that the phononic band gaps split in two and three transmission valleys for the three-material and the four-material based phononic structures, respectively. Furthermore, the number of transmission peaks between the split gaps is directly related to the number of unit cells composing the phononic structures. The observations of this work can be useful for the fabrication of acoustic filters with the possibility to select the transmission of particular frequencies.
