“…There are two ways to achieve this objective: one is shaping, which relies on the work of the designer; the other is using coated radar absorbing materials (RAMs). [1−6] Apart from the ordinary particle medium material, the other important research branch is the structural material, [7−11] especially the honeycomb structure, [12,13] because of its light weight, relatively high strength and stiffness, the material is widely used as a sandwiched layer. To get the reflection coefficient, we have to know the electromagnetic parameters of materials.…”

The interaction between particles cannot be ignored when a high frequency electromagnetic wave is incident on a mixed media. Strong fluctuation theory with correlation function is a suitable method to describe the problem. Materials with honeycomb sandwich structures with an absorber included are investigated. The effective electromagnetic parameters and reflection coefficient of these materials are deduced and numerical results are given. Compared with the method with a disturbing term not considered, this method shows better absorbing properties.

In this work we analyze the feasibility of a\ud broadband radar absorbing material made with an aeronautical\ud grade honeycomb panel, coated with a thin conducting film of\ud multilayer graphene nanoplatelets (MLGs). The film is deposited\ud over the surface of a phenolic-aramid sheet and characterized in\ud terms of sheet resistance and thickness. The morphology of the\ud multilayer graphene flakes is analyzed by atomic force and\ud scanning electron microscopies. The deposition parameters are\ud optimized in order to control the sheet resistance of the\ud conducting MLG film. The microwave broadband radar\ud absorbing properties of a MLG-coated phenolic-aramid\ud honeycomb panel are predicted through 3D electromagnetic\ud simulations. It is shown that with a panel thickness of 10 mm and\ud a sheet resistance of the MLG coating of 1238 Ω/□, the reflection\ud coefficient RdB has a minimum at 9 GHz. Moreover, it results\ud that the absorbing panel is broadband, with RdB≤ -10 dB in the\ud range from 5.5 GHz to 27 GHz
