QRCS Simulation of Equivalent Multi-Atom Model

In this paper, the QRCS of the equivalent multiatom physical model with additional random phase of [0,2pi] for each photon scattering process is proposed. Firstly, the interaction model between photons and atoms is established. Secondly, the QRCS results of different physical models of the equivalent multi-atom target, including one-dimensional linear target, two-dimensional planar target and three-dimensional cube target are derived. The influence of the shapes on QRCS is analyzed. The results show that when the additional random phase follows the uniformly distribution of [0,2 pi], the QRCS values of different models are almost the same at different angles. Finally, the proposed method is verified by simulations.
