We numerically investigated frequency characteristics of the multiple Josephson junctions (MJJ) model. MJJ with a constant current generates oscillating voltage. We find that the frequency characteristics depend on various patterns of rotating phase differences between superconducting layers. In MJJ with an alternating current we show harmonization of spontaneous and external oscillations. Our calculation also shows electromagnetic waves radiated from MJJ are coherent.
