A formula of the Josephson current in the presence of microwave and static magnetic field, taking finite wave-number effect into account, is derived. Finite wavenumber effect on ac Josephson current is discussed according to this formula. It can be used to explain such anomalous phenomena as missing of some rf-induced steps in the I-V curve, asymmetry of the I-V curves.
