The stationary state solutions of the Ising-type thin films with differentlayers in the presence of an external oscillatory field have been examinedwithin the effective field theory. The exhibition focuses on understanding ofthe external field frequency and amplitude effect on the overall behavior ofsystem for several powerful treatments. The particular attention has been paidon the dynamical parametric evolution of the special point at which thecritical temperature of the three-dimensional infinite bulk system, where thesurface and the modified exchange parameter are of no importance. Importantcharacteristics of the films, such as surface enhancement phenomenon, effect ofthickness on the dynamic process etc. have been introduced together with wellknown other characteristics. An attempt has been made to explain the relationsbetween the competing time scales (intrinsic microscopic relaxation time of thesystem and the time period of the external oscillatory field) and frequencydispersion of the critical temperature coordinate of the special point.
