Özet

A very promising amplitude-only microwave method is proposed to noniteratively determine the complex permittivity of lossy materials, which possess at least 10 dB attenuation. It utilizes reflection-only measurements, which in some instances increases the performance of the determination since the accuracy of transmission measurements significantly decreases for high-loss materials. The method is very feasible for industrial-based applications since the implementation of the method requires very simple microwave components or inexpensive microwave instruments. However, the method requires different reflection-only measurements, which in turn necessitates elaborate preparation of the sample holder.
