Transmission in the Phononic Octagonal Lattice Made of an Amorphous Zr55Cu30Ni5Al10 Alloy

Abstract

Structures with aperiodic layering are characterized by extremely interesting phononic properties. There is a phononic band gap phenomenon in them, so the waves with given frequency ranges do not propagate in these structures. These properties allow the use of such structures as selective filters or devices for noise control. The study examined transmission of the quasi one-dimensional octagonal structure. The properties of the aperiodic structure were analyzed depending on the network's generation number and layers thickness. The transmission matrix algorithm was used for the analysis. The tested lattices were made of an amorphous Zr55Cu30Ni5Al10 alloy immersed in water. The influence of water temperature on transmission peaks shifts was also studied.
