The surface-dressed optical Bloch equations and the Maxwell equations are combined consistently to obtain spontaneous decay rates and frequency shifts for an atom near the surface of a superlattice film with periodic or quasi-periodic structure. The effects of the number, thickness and dielectric properties of the layers constructing this film on the spontaneous emission properties are discussed. The results for the two different cases of periodic structure and quasi periodic structure are comparable.
