“…The magnitude of the RR forces is mostly determined by the ratio of the classical electron radius to the wavelength of the carrier (Landau & Lifschitz 1965). Until recent years this ratio has been seen as a small quantity, but in current and future experiments the effect of RR forces are planned to be magnified with field intensities and carrier frequencies large enough to affect the dynamics (Macchi 1992;Raynaud et al 2007;Wang et al 2012;Burton & Noble 2014;Fedeli et al 2016).…”

In the present analysis, we study effects of the radiation reaction (RR) on the dynamics of charged particles submitted to the action of localized longitudinal high-frequency carriers travelling at the speed of light. As the wave's crests and troughs keep overtaking particles, dissipative RR forces tend to drag particles alongside the wave in an effort to reduce the relative wave–particle speed. Particles of course never reach the phase velocity of the wave, but are instead driven to an ever-growing velocity, towards the speed of light, while in the wave localization region. We developed a modified average Hamiltonian formalism capable of describing the intricacies of the corresponding dynamics. The modified formalism agrees with simulations and is of particular usefulness in the study of optimum values for the localization length and maximum wave amplitude.
