Influence of PNM-0.38PT Defect on Transmission of Multilayer Periodic Phononic Structure

Influence of PNM-0.38PT Defect on Transmission of Multilayer Periodic Phononic Structure

In this work, the impact of the defect on the transmission of a mechanical wave in a periodic quasi-one-dimensional structure was investigated. The multilayer structure was made of PLA and air, while the defect layer was PNM-0.38PT with a significantly higher value of acoustic impedance in relation...
