An Experimental Model of the Acoustic Wave Propagation Through a Cascading Triple-Periodic Array of Cylindrical Holes
We study experimental acoustic properties of the meta-materials made as aluminum parallelepipeds with a crossed periodic system of through round holes. The experiments have been made with the use of industrial ultrasonic flaw detectors by the through-transmission technique in a wide interval of the ultrasonic frequencies. There is performed the analysis of the obtained temporary and spectral characteristics of the through-transmitted signal.
The work is performed under support of the Project № 15-19-10008-P by the Russian Science Foundation (RSCF).
