Shielding effectiveness of original and modified building materials

[摘要] This contribution deals with the determination of the shieldingeffectiveness of building materials used for office, factory and governmentbuildings. Besides the examination of standard materials, measurements werealso performed on modified materials, e.g. ferro concrete with enhancedshielding effectiveness due to a changed mixture or structure of thereinforcement. The measurements of original and modified materials werecarried out in a fully anechoic room (FAR) according to IEEE 299-1997 from 80 MHz up to 10 GHz.
