The bulk of the crystal is similar to that given in Fig. 1 . Web1 day ago · 1.Introduction. Phononic crystals (PnCs) are artificial metamaterials that constitute a periodically arranged individual in a mixture [1].PnCs were initially studied by Siglas, Economous and Kushwaha et al. [2, 3].PnCs can stop elastic wave or sound wave propagation within a specific frequency range [4], which is called the bandgap.Scientists …

These researches show that phononic crystal plays an increasing role ...
WebPhononic crystals are engineered structures that possess a regular ordering of regions with a contrast in their elastic modulus. Such structures can comprise of a single matrix … 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.

Some special characteristics such as negative refraction, self-collimation (SC), and forbidden band structure enable these structures to show different applications [ [23], [24], [25] ].
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.
