WebAn acoustic metamaterial, sonic crystal, or phononic crystal, is a material designed to control, direct, and manipulate sound waves or phonons in gases, liquids, and solids (crystal lattices). Sound wave control is … WebAug 4, 2024 · DISCUSSION. Our experimental data showed that heat conduction can be tuned using the wave nature of phonons; interference hinders phonon propagation in phononic crystals. Hence, a decrease of disorder yields a reduction in thermal conductivity, whereas in a high disorder state thermal conductivity remains unaffected. twin box slitter
