Its three main features are 1) it does not require any formal calibration procedure (calibration-free); 2) it is position-insensitive; and 3) it extracts ripple-free epsilon(r) due to gating process. The objective function derived to determine epsilon(r) by the proposed method is validated by free-space measurements of three dielectric samples (polypropylene, polyethylene, and polyoxymethylene). Besides, the accuracy of our method is compared with the accuracy of other calibrationfree and calibration-dependent methods in the literature.</dc:description><dc:publisher>IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC</dc:publisher><dc:date>2022</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/10799</dc:identifier><dc:identifier>https://doi.org/10.1109/tim.2022.3153991</dc:identifier><dc:identifier>0018-9456</dc:identifier><dc:language>en</dc:language><dc:relation>IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/10799</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
