By use of a recently developed multi-scale simulation method, we re-investigate terahertz wave emission with motions of Josephson vortices, as a possible mechanism for enhancing the emitted power. Results show that there appears a strong wave emission around the n = 2 cavity mode (one-wavelength mode), when motions of vortices and cavity modes are resonate.
