Abstract

Since the development of advanced electromagnetic absorption materials is highly critical in telecommunication and stealth technology, both fabrication technology and structure design are significant in achieving broadband and strong absorption performance. For understanding the effects of fabrication technology and structure design on performance, in this work two fabrication methods, including the traditional mixing and novel framework method, are demonstrated to investigate the dispersion capability of reduced graphene oxide in polymeric matrices. Moreover, artificial structure designs, including the layers of unit cells, top-layer shape and top-layer materials, are used for further optimizing the microwave absorption performance. A performance comparison suggests that fabrication via framework technology is more favorable to obtain an ideal impedance match in the composites. Additionally, the meta-structural design coupled with the related mechanism for substantially broadening the absorption bandwidth has been systematically discussed. The results imply that the combination of fabrication technology and periodic pattern design provides a promising platform for achieving high-performance absorption materials.
