We have studied the properties of the amplitude- N -th powered squeezing of an electromagnetic field in the k -photon Jaynes-Cummings model of an atom initially being in the ground state and coupling with the superposition state. The results show that, under the condition of n ⩾ k , where n is the photon number of the superposition state, the field exhibits not only the amplitude- N = n -th powered squeezing but also the amplitude- N = ( n /2)-th powered squeezing for even n . The variations of the amplitude- N -th powered squeezing of the field with the powers N and k are discussed.
