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 ( S 21) 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
