Abstract: We find the quasinormal modes of the charged scalar and Dirac fields in thebackground of the rotating charged black holes, described by the Kerr-Newman-deSitter solution. The dependence of the quasinormal spectrum upon the black holeparameters mass M, angular momentum a, charge Q, as well as on values of the\Lambda-term and field charge q is investigated. Special attention is given tothe near extremal limit of the black hole charge. In particular, we find thatfor both scalar and Dirac fields, charged perturbations decay quicker for q>0and slower for q<0 for values of black holes charge Q less than than somethreshold value, which is close to the extremal value of charge and depend onparameters of the black holes.
