ab: Summary: The phase dynamics of intrinsic Josephson junctions (IJJ) in high
    temperature superconductors is investigated. We calculate numerically
    the current-voltage characteristics (CVC) of IJJ in the framework of
    the capacitively coupled Josephson junctions model with diffusion
    current. The effect of electromagnetic irradiation on the CVC of
    coupled Josephson junctions is demonstrated. Variation of the Shapiro
    steps and of the critical current with the radiation amplitude is
    systematically studied for a single junction. These results are
    generalized for a stack of coupled Josephson junctions. The effects of
    coupling between junctions on the Shapiro steps in the CVC and on the
    electric charge oscillations in the superconducting layers at the
    parametric resonance are shown.
