The human brain model and the skin model that were used in our experiments have five layers and seven layers  the separation distance of source and detector should be approximately eight millimeters. Future work was discussed at the end of the paper. 2009 IEEE.  respectively. The backscattered intensity from every layer of the human tissue model was obtained by marking the deepest layer that every photon can reach. The simulation results of brain model indicated that the source-detector separation distance should be selected at three centimeters for studies on the actions of the brain nerve cells   The separation methods and station keeping algoriths for multi-geos collocation 会议论文 作者:  Li, Hengnian;  Gao, Yijun;  Li, Jisheng 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/18 GEO satellites  Mathematical derivation  Physical separation  Radio frequencies  Relative distances  Separation distances  Separation methods  Station keeping   The strategies and algorithms study for multi-GEO satellites collocation 期刊论文 Yuhang Xuebao/Journal of Astronautics, 2009, 卷号: 30, 期号: 3, 页码: 967-973 作者:  Li, Heng-Nian;  Gao, Yi-Jun;  Yu, Pei-Jun;  Li, Ji-Sheng;  Huang, Yong-Xuan 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/18 Collision risks  Collocation separation strategies  Combined E-I separation  GEO satellites  Minimal distance  New strategy  Orbit parameters  Orbital element  Physical separation  Radio frequencies  Relative distances  Separation distances  Station keeping
