We propose a generic scattering matrix model implementable in photonics to engineer new Floquet metallic phase that combines two distinct topological properties: the winding of bulk bands and existence robust chiral edge states. The gives rise wavepacket oscillations real space while conserving its initial momentum. Our findings open way study class systems.
