Modelling dielectric and magnetic properties of ferroconcrete

[摘要] This contribution discusses the modelling and parameterization of dielectricand magnetic properties of ferroconcrete by using numerical electromagneticfield analysis software. The software is based on the Method of Moments(MoM). The shielding effectiveness (SE) of the ferroconcrete DUT was alreadymeasured in a study by order of the government. According to these results,the ferroconcrete DUT is modelled and calculated. Therefore the DUT issubdivided into two parts. The first part represents the reinforcement mesh;the second part represents the lossy concrete with complex permittivity.Afterwards, the reflection and transmission properties of numerical analysedbuilding materials are validated and compared with the measurement resultsin a frequency range of 30–1000 MHz.
