【摘要】 在短距离通信中,墙体是信道中的主要障碍。目前许多建筑都采用混凝土墙或钢筋混凝土墙的结构,这些墙体在一定程度上影响着电磁波的传输。本文采用时域有限差分法(FDTD)研究了一些实际中典型的墙体结构参数对电磁波传输的影响。研究分析了哪些结构因数影响了电磁波的传输以及如何影响,得出常用的建筑所采用的钢筋混凝土墙的厚度、钢筋的直径和钢筋网格的边长等墙体结构与电磁波传输系数的具体关系并给出实验仿真的结果。更多还原

【Abstract】 In short distance communications,walls are the main obstacles in channel.Nowadays,many structures and buildings use concrete or reinforced concrete walls.These walls affect transmission of EM wave at some degree.This paper analyses the effects of some typical structural parameters of walls on transmission of EM wave using a finite-difference time-domain(FDTD)solution of Maxwell’s equations.We analyze that which factors affect transmission of EM wave and how these factors affect it.We result that the relationship of the thickness of reinforced concrete wall、the diameter of the rebar、the size of the rebar lattice(which are in common use)and the transmitted coefficient.更多还原
