Calibration-Free Time-Domain Free-Space Permittivity Extraction TechniqueHasar, Ugur C.Ozturk, GokhanKaya, YunusErtugrul, MehmetFree-spacepermittivityreflectiontime-domainA time-domain free-space technique has been proposed to extract relative permittivity ( _r ) and effective conductivity ( σ _e ) of low-loss dielectric samples using their metal- and air-backed calibration-free reflected powers. Numerical computations and 3-D electromagnetic simulations were performed to validate the method. A sensitivity analysis was carried out to examine its accuracy. Calibration-free time-domain free-space measurements over 1-12 GHz were conducted by VNA to extract _r and σ _e of polyethylene and polypropylene low-loss samples.Institute of Electrical and Electronics Engineers Inc.2022Articlehttps://rdlopen.rawdatalibrary.net/r/bayburt/11989https://doi.org/10.1109/tap.2021.31211330018-926XenIEEE Transactions on Antennas and Propagationinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/11989
