Nanoparticles of barium and strontium Titanates/epoxy resin as microwave absorbers

Microwave absorber materials play a major role in electromagnetic interference and compatibility measurements in anechoic chambers. The authors have made efforts toward finding the reflection co-efficient of barium titanate (BaTiO₃)/ epoxy resin composites and strontium Titanates (SrTiO₃)/epoxy resin [1] were made as films with two different concentrations. The measurement was carried out by a transmission/reflection method using a vector network analyzer R&S: ZVT8 in the frequency range of 8 GHz - 12.5 GHz (X-Band). The results are analyzed at the end for the suitability of the material in the X-band. The basic material characteristics are also discussed briefly.
