1、 Information Classification:General An improved broadband material characterization method Feng-Nan(Leon),Wu,Samtec Leon.W,+886 939163668 Xingling(Mick),Zhou,Samtec Mick.Z Tony,Chen,Samtec Tony.C Information Classification:General Abstract We propose an enhanced broadband material characterization t

2、echnique for extracting dielectric constant(Dk)and loss tangent(Df)in high-speed interconnect applications.The method uses two coaxial airlines of different lengths(50mm and 60mm),measured with and without the material under test(MUT),combined with Automatic Fixture Removal(AFR)for precise S-paramet

3、er de-embedding.This technique avoids reference-plane alignment and physical length dependency by leveraging propagation constant relationships which differ from NRW/NIST approaches.Closed-form equations derived from multilayer lossy coaxial theory eliminate metal loss and geometric tolerances.The D

4、jordjevicSarkar model extends bandwidth beyond 40GHz,validated through 3D-printed HT200 samples and Swissto12 waveguide kit measurements.Results demonstrate accuracy,scalability,and immunity to manufacturing tolerances,enabling future characterization up to 100GHz and beyond.Author(s)Biography Leon
