By applying the interplay among the nodal points of partial waves along with the concept of streamline in fluid dynamics for probability flux, we provide a method not only making a nanoparticle nearly invisible, but also hiding its interior region from the outside probing matter wave. A quantum invisible cloak to the electron transport in a host semiconductor is demonstrated by, simultaneously guiding the probability flux outside a hidden region and keeping the total scattering cross section negligible [1]. Based on the scattering theory, we propose a phase diagram to reveal all possible solutions of Mie theory for the design of nano-particles. Power assignment for different scattering channels and related physical boundary requirement become easily accessible in such a phase diagram.
