Terahertz time-domain ellipsometry with spintronic emitters: Pauli coefficients as a superior alternative to Jones and Mueller matrices

Pierre Koleják, Jiaming Liu, Robin Silber, Martin Mičica, Ondřej Ballada, Čestmír Barta, Romain Lebrun, Nicolas Tiercelin, Mathias Vanwolleghem, Kamil Postava

We introduce terahertz complete time-domain spectroscopic ellipsometry (THz-cTDSE), extending traditional ellipsometry by determining full Jones and Mueller matrices for in-depth material characterization. This marks the first application of spintronic terahertz emitters in ellipsometry, achieving...
