We study the properties of the classical electromagnetic (EM) radiationproduced by two physically different yet closely related systems, which may beregarded as classical analogues of the Dynamical Casimir Effect (DCE). Theycorrespond to two flat, infinite, parallel planes, one of them static andimposing perfect conductor boundary conditions, while the other performs arigid oscillatory motion. The systems differ just in the electrical propertiesof the oscillating plane: one of them is just a planar dipole layer(representing, for instance, a small-width electret). The other, instead, has adipole layer on the side which faces the static plane, but behaves as aconductor on the other side: this can be used as a representation of aconductor endowed with patch potentials (on the side which faces the conductingplane). We evaluate, in both cases, the dissipative flux of energy between thesystem and its environment, showing that, at least for small mechanicaloscillation amplitudes, it can be written in terms of the dipole layerautocorrelation function. We show that there are resonances as a function ofthe frequency of the mechanical oscillation.
