Microwave Characterization of Pb0.45Ca0.55(Fe0.5Nb0.5)1−x Sn x O3 Multiferroics at X-Band

Abstract

The microwave characteristics of Pb 0.45 Ca 0.55 (Fe 0.5 Nb 0.5 ) 1Àx Sn x O 3 multiferroics (x = 0.03, 0.06, 0.09, 0.12, 0.15) have been investigated as a function of frequency (8-12 GHz) and thickness for different substitutions of Sn 4+ ions. The absorber testing device method is used to study microwave properties in the rectangular slotted waveguide. The condition of microwave signal after passing through different compositions has been reported. The quarter wavelength criterion is used to evaluate the microwave absorption. The large microwave absorption is observed at lower as well as higher substitution. Maximum reflected power has been found at higher substitution. The different compositions for electromagnetic applications have also been put forth.
