4. Terahertz Talks: New Frontiers in Material Characterization (Dr.-Ing. Jan Barowski)

Terahertz Talks is a webinar series with live discussions and Q&A sessions tailored for scientists, researchers, and industry professionals looking to deepen their expertise and stay ahead in the field of terahertz technology. 🧭 Outline 0:00 – Introduction 5:43 – Fundamentals & Principles 11:25 – Transmission Line Methods 16:38 – Extraction of the Relative Permittivity 21:04 – Experiments & Applications 43:57 – Summary 💬 Q&A Session (50:22) 1️⃣ (50:22) You have shown us a lot about the characterization of materials, particularly the determination of the dielectric properties. Many industrial applications are not per se interested in these numbers — why is it important to know these when monitoring a production process, for example in extrusion? 2️⃣ (52:20) What are the benefits of electronic and radar-based measurement techniques compared to other non-destructive testing methods? 3️⃣ (54:41) Which method would you suggest for high-frequency conductivity measurement of low-conductivity materials? 4️⃣ (56:10) Could you give an estimate of the accuracy of the presented free-space methods — in terms of εᵣ and tan δ, especially for low-loss dielectrics? 5️⃣ (56:58) Would these methods be feasible in the lower GHz region (1–30 GHz)? 6️⃣ (58:10) How can current limitations in radar-based techniques be overcome — for example, to measure thinner materials or to increase resolution in radar images? 7️⃣ (1:00:00) What are the prospects of these systems — where are current trends going?
