Signal propagation is affected by the characteristics of the materials in the medium. Therefore, information about material properties is of paramount importance when radio propagation is investigated. In this article, the measured complex relative permittivity of 20 common materials in indoor environments (including plastics, wood and woodbased materials, glass, gypsum plaster and plasterboard, brick, and concrete) across the frequency band of 0.2-67 GHz is shown. The dielectric properties are measured by using two open-ended coaxial probes. The single-pole Cole-Cole model is employed for fitting the measured data since most of the materials follow it. Moreover, fitting parameters for the multipole Debye model, which can be used instead of the Cole-Cole [it is more appropriate for finite-distance, timedomain (FDTD) applications], are given. Thus, an easy way for obtaining the data is provided, which can be helpful when wideband propagation is considered.

用于超宽带传播研究的常用建筑材料的介电特性 [测量角]

信号传播受介质中材料特性的影响。因此，在研究无线电传播时，有关材料特性的信息至关重要。在本文中，显示了在 0.2-67 GHz 频段内测得的室内环境中 20 种常见材料（包括塑料、木材和木质材料、玻璃、石膏和石膏板、砖块和混凝土）的复相对介电常数。通过使用两个开放式同轴探头测量介电特性。单极Cole-Cole模型用于拟合测量数据，因为大多数材料都遵循它。此外，还给出了多极德拜模型的拟合参数，该模型可用于代替 Cole-Cole [它更适合有限距离、时域 (FDTD) 应用]。因此，
