The dispersion relations of 。Acoustics phonon In periodic structure

Abstract: Some dispersion relations of acoustic in periodic structure are studied in detail in the article.Firstly, the dispersion relations of acoustic phonon dispersion relations are studied in Unidimensional and Two-dimensional atomic periodic structure by Newtonian mechanics. Secondly, dispersion relations of acoustic phonon in A- B periodic structure and the macro- surface dispersion relations of acoustic phonon in A- Bฟ periodic stru★cture contains defact are studied by Solids theory .
