该文件是模拟电磁波传播过程中遇到障碍物遮挡使信号与接收装置之间不能直视而产生的传输误差，对模拟电磁波传播具有很大帮助。(The file is a simulation of the transmission error caused by the obstacle occlusion in the process of electromagnetic wave propagation, which can not be seen directly between the signal and the receiving device. It is of great help to the simulation of electromagnetic wave propagation.)
