Transport through the quantum wire with many side-coupled quantum chains is investigated by using a recursive Green's function technique. We obtained the modulation rules of the parameters N and NU, which are the number of side-coupled quantum chain and the quantum-dot number of side-coupled quantum chain, respectively. The results show that the recursive Green's function method not only can conveniently tune the model and the number of the quantum chain, but also can be applied to study the varied nanofabrication of quantum devices.
