  The formation of pulses of surface electromagnetic waves in a
metal/dielectric interface is considered in the process of cooperative decay of
excitons of quantum dots distributed near a metal surface in a dielectric
layer. It is shown that the efficiency of exciton energy transfer to excited
plasmons can be increased by selecting the dielectric material with specified
values of the complex permittivity. It is found that in the mean field
approximation the semiclassical model of formation of plasmon pulses in the
system under study is reduced to the pendulum equation with the additional term
of nonlinear losses.
