Abstract
As the modern development of electronic device smaller and smaller, quantum effect would become significant. Thus extending the concept of quantum mechanics into design of new electronic devices becomes more important. Controlling the movement of these electrons plays the central role in this issue. In this work, we propose a new quantum cloaking mechanism which has completely different to the previous work of Liao et al [1]. This mechanism is based on the scattering cancellation and the interplay among the nodal points of partial waves, that one can simultaneously guide the probability flux outside the interior and keep the total scattering cross section negligible. Moreover, we can put any electric devices inside quantum cloaking without affecting outside probability of matter wave. With the analogy between quantum matter waves and classical waves, the concept of our method can be applied in other fields, such as electromagnetic and acoustic systems, etc. © 2014 IEEE.
