QUASI-PARTICLE DAMPING OF JOSEPHSON PLASMA MODE IN LAYERED SUPERCONDUCTORS

We examine electronic dissipative properties of levered superconductor s when the de magnetic field is applied. Assuming a tunneling nature o f the c-axis transport that consists of Josephson (JT) and quasipartic le (QT) parts, the non-stationary processes are considered. We obtain that in whole temperature range below T-c, the damping of the Josephso n plasma mode is significantly determined by both JT and QT. Also we f ind that influence of the applied de magnetic field on the Josephson p lasma frequency is limited because only JT component is suppressed, wh ile QT remains unaffected.
