Investigating the effect of honeycomb structure composite on microwave absorption properties

In this report, we designed and fabricated carbon-coated honeycomb microwave absorbing materials (HMAMs), which were lightweight with high stiffness and exhibited broadband performance. The effect of structural parameters such as pore size, honeycomb height, coating thickness, permittivity and dielectric dissipation factor of the coating, on the microwave absorption was analyzed in detail. An effective homogeneous model was established through...
