  The emission of electromagnetic waves from a system described by the
H\'enon-Heiles potential is studied in this work. The main aim being to analyze
the behavior of the system when the damping term is included explicitly into
the equations of motion. Energy losses at the chaotic regime and at the regular
regime are compared. The results obtained here are similar to the case of
gravitational waves emission, as long we consider only the energy loss. The
main difference being that in the present work the energy emitted is explicitly
calculated solving the equation of motion without further approximations. It is
expected that the present analysis may be useful when studying the analogous
problem of dissipation in gravitational systems.
