To the Ballistic Dimer Resonance in the Propagation of Mechanical Waves in One Dimensional Linear Lattice

H. Khalfoun, M. Bouamoud and S. Bentata

Abstract:
The propagation of mechanical waves in one-dimensional Kronig-Penney random media is examined in presence of short-range binary correlation in disorder. A chain of harmonic oscillators is connected to a rigid foundation by linear springs while a string submitted to a uniform tension relates masses to each other. Using the transfer matrix formalism, the nature of the propagating modes is numerically investigated with the study of the transmission coefficient and the localization length. An interesting manner to construct the dimer unit cell is presented settling down the ballistic regime. The presence of such a particular dimer resonance provides the Bloch extended vibration modes in contradiction with the general conclusion of the localization phenomena in one-dimensional disordered system.
