近年来，材料在微波频率下的性能在商业和工业上引起了广泛的兴趣。然而，微波能量和铁化合物之间的相互作用是一个领域，需要进一步的表征工作。本文提出了一种新的优化分析-数值方法，用于将平滑透射散射（）参数转换为复介电常数。测量方法进行了验证，并随后用于表征改性聚丙烯腈催化剂粉末的介电性能，将配位铁阳离子。将结果与在1至4 GHz的相同频率范围内测量的其他公开的铁催化剂材料进行比较。© 2014 Wiley Periodicals，Inc.微波光学技术快报56：2671-2676，2014年
Materials performance at microwave frequencies has generated a wide interest in recent years for commercial and industrial purposes. However, the interaction between microwave energy and iron compounds is an area where further characterization work is required. The article presents a novel optimized analytical‐numerical method for conversion of smoothed transmission scattering ( ) parameters to complex permittivity. The measurement method was validated and subsequently used to characterize the dielectric properties of modified polyacrylonitrile catalyst powder incorporating ligated iron cations. The result is compared to other published iron catalyst materials measured in the same frequency range of 1 to 4 GHz. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2671–2676, 2014
