A quantum well wire system with lateral parabolic confinement, partly irradiated by intense terahertz laser radiation, is considered. Using the exact electronic states of the system in the presence of the laser field, the transmission probabilities for the sideband components of the electronic states, through the irradiated region, are obtained. Then by considering the scattering of the emerging electronic states by a -function scatterer in a formalism based on the Lippmann-Schwinger approach, the contribution of the sideband components in the transmission coefficients and the conductance of the wire are determined. Results indicate the possibility to control the transmission pattern across the wire.
