We carry out the study of a solution of the coupled equations of the theory known as Einstein-Maxwell-Dilaton-Axion (EMDA) with the purpose of obtaining information of the coupling of the scalar fields with the U(1)gauge fields. To obtain a solution of the equations of EMDA we consider a metric that possesses two space-like Killing vectors, later the metric is transformed into an Einstein-Rosen metric where can interpret the space-time as either: a cylindrical space, a plane wave space, or a cosmological model. The cosmological model is studied in its kinematics, possible singularities, and the asymptotic behavior of the fields and the metric. We observe that the metric near the singularity has a behavior of the type "asymptotically velocity-term dominated'" (AVDT).
