Study of a Coplanar Circulator Based on a Barium Hexaferrite Nanocomposite

Abstract : This paper presents the design and analysis of a Y-junction coplanar circulator operating in the frequency range of 40{60 GHz. The magnetic material used in this circulator's numerical study is a Barium Hexaferrite with a magnetization lower than the usual ferrite. Its purpose is to assume the performance of such circulator when its conventional ferrite is replaced by a magnetic nanocomposite. Magnetization depends on the volume of the magnetic material; therefore, the volume fraction of the barium hexaferrite nanoparticles in the ¯nal nanocomposite is introduced. A three dimensional ¯nite element method was used to evaluate numerically the circulator's performance. Preliminary experiments on the nanocomposite magnetic material showing its orientation and non-reciprocity are presented.
