Abstract

Incorporating reduced graphene oxide (RGO) with Co/Co₃O₄ gives rise to the enhancement of the electromagnetic wave absorption of the composite, contributed from the excellent electric property and the unique architectural morphology of RGO. The complex permeability and complex permittivity are investigated in the range of 1-18 GHz. The reflection loss R_L of the Co/Co₃O₄ /RGO composite shows higher performance than that of the Co/Co₃O₄ composite due to the unique electronic property coming from the RGO. The frequency and the thickness of the absorber, of which the peak R_L value occurs, derived from the transmit-line theory agree well with the results from the quarter-wavelength matching principle. Hence, the Co/Co₃O₄ RGO composite is one of the promising candidates for microwave absorption.
