The paper studies photon-associated transmission through a quantum wire with a side-coupled stub tuner, to which an external microwave field applies, in terms of the approach developed by Cai. The inelastic scattering of an incoming electron and the photon field lead to photon-electronic transmission though quantum wire. It is found that single photon absorbing (emitting) of the incoming electron in the stub can bring about antiresonant transmission in the quantum wire. The influence of the feedback mechanism from inelastic scattering process on elastic channel transmission is also examined. Total transmission coefficient as a function of photon energy exhibits non-periodic oscillation peaks. With the increasing of photon-electron coupling constant, the amplitude of these oscillation peaks enhances.
