Improved accuracy has been shown by the applied uncertainty analysis. For the validation of our method, ϵr of low-loss and lossy samples was extracted.</dc:description><dc:publisher>American Institute of Physics Inc.</dc:publisher><dc:date>2017</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/665</dc:identifier><dc:identifier>https://doi.org/10.1063/1.4997076</dc:identifier><dc:identifier>0034-6748</dc:identifier><dc:language>en</dc:language><dc:relation>Review of Scientific Instruments</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/665</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
