Braneworld models involving large extra dimensions have been very useful in addressing several open questions in high energy physics. Most of the braneworlds are realized as time-independent field configurations. However, there have appeared several braneworld models that assumed time-dependent metrics and fields. In this paper we study the non-stationary 6D braneworld generated by standing gravitational waves coupled to a phantom-like bulk scalar field. The model is generalization of 5D standing waves scenario. The metric we use differs from those of the 6D models. In the work is developed matter localization and cosmological solutions.
