Phononic crystals for shaping fluids
WebThree classes of phononic crystal can be defined, which differ from each other by the physical nature of the inclusions and the matrix. One can thus define solid–solid, fluid–fluid, and mixed solid–fluid composite phononic crystals. The opening of wide acoustic band gaps requires two main conditions.

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. iny miny miney moe lyrics
