The Experimental Study of a Metamaterial with a Triple-Periodic Microstructure on the Epoxy Base
We perform an experimental investigation of the acoustic properties of a metamaterial consisting of triple periodic system of metallic spheres, coated with an epoxy resin. Comparisons are given with the replacement of the wave propagation medium from an epoxy base to water and ice. Then we consider the case of aluminum specimens with holes filled with water and ice. A detailed analysis of the experimental data is performed.
The work is performed within the framework of the Project № 15-19-10008-P of the Russian Science Foundation (RSCF).
