Synthesis of La2O3/PVA thin film for microwave device application

Abstract

Lanthanum Oxide thin film was synthesized using Polyvinyl Alcohol (PVA) to understand its microwave interaction. The experiment was performed in the X-Band under the frequency range of (9-11.5 GHz) for understanding various materialistic and microwave properties of the material. Scattering parameters were analyzed for understanding the reflection coefficient(S11) and transmission coefficient(S12) of the thin film. The reflection coefficient varied from –30dB to –38.4dB, the increase in reflection with increase in concentration was observed which results in smoothing of the surface due to concentration doping.
