摘要：

Fe3O4/CuPc hybrid material, where the CuPc not only interlinked but also be embedded within the Fe3O4 microspheres, was synthesized via solvothermal method. The electromagnetic properties of the sample showed cooperative nonlinear dielectric/magnetic resonance in X-band and Ku-band. The proposed equivalent filter circuit model well explained the dual nonlinear dielectric resonances. The magnetic resonances were proposed to be generated from the natural resonance of the Fe3O4 and heterogeneous interfaces in/between microspheres severally. The microwave absorption of the sample obtained two optimal nesting peaks of -35 and -33 dB at 12.6 and 15.8 GHz with thickness of 2.6 and 1.8 mm respectively. (C) 2011 Elsevier B.V.
