Abstract
In this work we study numerically the existence of gap solitons in an acoustic media. To approach the problem a set of coupled-mode equations are given. In order to obtain a solitary wave in a real media, it is necessary of two phenomena, dispersion and nonlinearity. Acoustic media, usually can present nonlinearity but also low dispersions. To increase dispersion, it is proposed to use a multi-layered medium, a kind of sonic crystal in 1D, that it is demonstrated to have high dispersion near some frequency bands. In this kind of media, it is possible to observe soliton waves.
