Electromagnetic properties in the multi-Josephson junction model with a Josephson vortex lattice

By use of the multi-Josephson junction model, we investigate the electromagnetic properties of high-Tc superconductors, by deriving coupled equations among phase differences and electromagnetic fields inside and outside of junctions. We consider both of the capacitive and inductive effects. Relation between Josephson plasma modes and Josephson vortex lattices is discussed by calculating the reflectivity. Below the usual Josephson plasma edge, there appear structures of absorption due to collective motions of Josephson vortices. Emission of the electromagnetic field from the boundary wall is also investigated in various conditions, and relation between vortex motions and emitted modes will be discussed.
