Elastic properties of ABS-plastic acoustic metamaterial produced by 3D-printing method

Metamaterial samples with different filling (air and metal) were fabricated from ABS-plastic using 3D printing. It was experimentally shown how filling, geometry and polarization vector orientation for shear wave affect frequency response of bulk acoustic waves in the frequency range from 0.2 MHz to 3 MHz. The results of experimental investigations show the possibility of creating solid-state analogue filters for broadband signals of transverse acoustic waves.
