  In this work we consider electromagnetic dynamics in Randall-Sundrum branes.
It is derived a family of four-dimensional spacetimes compatible with
Randall-Sundrum brane worlds, focusing on asymptotic flat backgrounds. Maximal
extensions of the solutions are constructed and their causal structures are
discussed. These spacetimes include singular, non-singular and extreme black
holes. Maxwell's electromagnetic field is introduced and its evolution is
studied in an extensive numerical survey. Electromagnetic quasinormal mode
spectra are derived and analyzed with time-dependent and high-order WKB
methods. Our results indicate that the black holes in the brane are
electromagnetically stable.
