Research of Metal-Dielectric Sandwich Structures for Real-Time Imaging of Microwave Radiation

Abstract

Results of measurements of transmission, reflection and absorption of dielectric substrates are given in article. The mica substrate and a polyimide substrate were probed. The thin layer of nichrome, a thin layer of carbon and a monolayer of carbon were used as absorbers. Cholesteric liquid crystal and Al-VOx structure were used as a thermosensitive layer. Measurements were taken on installation based on R&S ZVA Vector Network Analyzer in the range of 170-260 GHz. Probed structures can be used in devices for imaging of microwave radiation.
