摘要
近十年来,随着室内无线系统迅速发展,钢筋混凝土墙对电磁波的反射与透射的研究成为热点。文中将矩量法与格林函数法相结合,对2.4 GHz的电磁波在钢筋混凝土墙中的反射与透射特性进行仿真。结果表明,钢筋条的存在产生了线线交感,使得电磁波的传播特性变得更为复杂,因而反射与传播系数的概念不再适用于定义钢筋混凝土墙的传播特性。
The proliferation of indoor wireless system over the past decade has generated great interest in the reflection and transmission properties of reinforced concrete. This paper combines numerical analysis with asymptotic analysis to model the reflection and transmission properties of a kind of reinforced concrete for 2.4 GHz band. As a result, the existence of wires produces the wire- wire interactions,which make the reflection and transmission properties of reinforced concrete more complicated,so the concept of reflection and transmission coefficients can not be used to characterize a dielectric slab.
