Comparison of phononic structures with piezoelectric 0.62Pb(Mg_1/3Nb_1/3)O₃-0.38PbTiO₃ defect layers

Three types of multilayer structures were analyzed in the work: binary (periodic), Thue-Morse (quasiperiodic) and Severin (aperiodic). Layers in the structures were made of water and epoxy. In the given structure occurring layer were changed sequentially to layer made of a 0.2mol% Fe-doped relaxor-based ferroelectric 0.62PB(Mg_1/3Nb_1/3)O₃-0.38PbTiO₃ (PNM-0.38PT). The tests were carried out for the ultrasonic frequency range from 500 kHz to 700 kHz. As part of the calculations, the transmission characteristics of structures with defects were obtained. In Thue-Morse structure all the characteristics were different, but in the binary and Severin structures, the same transmission values were observed for different types of structures.
