Abstract

Emission of THz electromagnetic waves from BSCCO mesas covered with normal electrodes is numerically studied. We discuss the electromagnetic excitations corresponding to π- and 2π-cavity modes in a stack of intrinsic Josephson junctions with a thickness of ∼1μm and a width of ∼100μm, using the "coarse-grained" xz-model. It is shown that the AC electromagnetic field excited inside the junctions is nearly perfect standing-wave mode and then the emission takes place mainly from the electrodes.
