| Popis: | The study investigated the propagation of a mechanical wave in a two-dimensional phononic structure. The influence of material from which metaatom rods were made on the phononical properties of the structure was investigated. Rods made of amorphous Zr55Cu30Ni5Al10 and polypropylenes were compared. The Finite Difference Time Domain (FDTD) algorithm was used to carry out the simulation. Next, theoretical and experimental analysis of the intensity of the mechanical wave was carried out. Frequency response of a regular phononic structure was also analyzed. |
