This article will focus on the free space measurement technique, from which a series of optimization algorithms have been developed, allowing the extraction of permittivity and permeability of materials in a frequency range up to 40 GHz using the Time-Domain Gating from a Vector Network Analyzer (VNA).engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttps://creativecommons.org/licenses/by-nc-nd/4.0/Optimization algorithmsFree-space methodScattering parametersTime-domain gatingMaterial characterizationNon-destructive testingPermeabilityPermittivityinfo:eu-repo/semantics/conferenceObject10.23919/EuCAP57121.2023.10133519info:eu-repo/semantics/openAccess
