Interaction with external time-dependent fields in low-dimensional systems leads in many cases to completely new phenomena of electronic transport. Dealing with a driven system, its quantum dynamics is adequately analyzed in terms of the Floquet or quasienergy spectrum. In this paper, we extend the effective mass model to the case of different effective masses for different materials in a heterostructure. For this case we present a general method which allows us to treat a time modulated potential acting upon a quantum well structure. We extend the work of Wenjun Li and LE Reichl,[1], and consider the case of a multilayer composed of different materials, assuming th
