摘要
This study deals with the development of a unified model for the design of microwave absorbers. This tool unifies the modeling of electromagnetic properties of composite materials and the modeling of microwave absorbers made of these composites. It makes it possible to calculate thickness and formulation of the composite that allows minimizing reflectivity. It takes into account shape effects linked to microstructure and is valid for dielectric and magnetic materials. The design of a bilayer screen made of polymers loaded with ferromagnetic particles is given as an example. This tool can be used to help radar absorbing materials manufacturers in the formulation of materials dedicated to a specific band of frequencies.
