We present a theoretical study on the effect of radiation on the\nmangetoresistance of two-dimensional electron systems with strong Rashba\nspint-orbit coupling. We want to study the interplay between two well-known\neffects in these electron systems: the radiation-induced resistance\noscillations and the typical beating pattern of systems with intense Rashba\ninteraction. We analytically derive an exact solution for the electron wave\nfunction corresponding to a total Hamiltonian with Rashba and radiation terms.\nWe consider a perturbation treatment for elastic scattering due to charged\nimpurities to finally obtain the magnetoresistance of the system. Without\nradiation we recover a beating pattern in the amplitude of the Shubnikov de\nHass oscillations: a set of nodes and antinodes in the magnetoresistance. In\nthe presence of radiation this beating pattern is strongly modified following\nthe profile of radiation-induced magnetoresistance oscillations. We study their\ndependence on intensity and frequency of radiation, including the teraherzt\nregime.\n
