In this communication we study the interaction between a two-level atom and an electromagnetic field in the presence of the classical field and Kerr-like medium. Under a certain condition the system is transformed to the usual Jaynes-Cummings model. The atomic inversion is investigated where the phenomenon of super-structure is reported for a large value of the classical field coupling parameter. Our results show that the information of variance and entropy squeezing beside the purity can be controlled by both of the coupling parameter of the classical field and the Kerr-like medium parameter.
