In this work we present results obtained on the transport properties of a wave packet in a quantum wire subjected to an external modulated electric field and taking into account the spin-orbit interaction of the Rashba and Dresselhaus types. In this system the Dresselhaus spin-orbit interaction produces the reversal of the spin of the injected electron. To analyze the time evolution of the system (particle) we evaluate the following parameters: the return probability of electron , the root mean square deviation (MSD) function participation and the center of the wave packet. It was observed that for certain parameter values the wave function is localized in a certain region which allows to make a correlation with a metal-insulator phase transition.
