Synthesis and characterization of Mg–Zn ferrite based flexible microwave composites and its application as SNG metamaterial

Abstract In this article, we propose SNG (single negative) metamaterial fabricated on Mg–Zn ferrite-based flexible microwave composites. Firstly, the flexible composites are synthesized by the sol-gel method having four different molecular compositions of MgxZn(1−x)Fe2O4, which are denoted as Mg20,...
