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. WebPhononic crystals are usually referred to structures in which the main mechanism of dispersion is Bragg reflection, therefore, the periodicity and position of scatterers is a very important element in forming the desired properties.
