A simple theory for the Aharonov-Bohm-like effect (dynamical phase) in semiconductor microstructure, is presented in a paper, assuming a "ballistic spin transport". If in one of the arms of microstructure there is an additional periodic magnetic field, the spin wave function acquires a phase shift due to additional spin precession about that field. By introducing quaternion representation of the elements of propagation matrices, one can calculate the transition coefficient of the structure. It is shown that the deep modulation of the conductance could be achieved.
