Mimic materials electromagnetic reflection and transmission coefficient

The paper is focused on a design method to build layered materials able to mimic the reflection and transmission coefficient profile of really existing or even invented dielectric materials. The design method is based on particle swarm optimization algorithm and electromagnetic matrix formalism which allows the minimization of an objective function. Goal of the procedure is to obtain a layered materials mimicking the target reflection and transmission coefficient profile a priori established. The design algorithm is coded in Matlab and it selects the best material for each layer by accessing to a database of dielectrically characterized materials. Materials in the database are made using different species and amount of carbon nanomaterials dispersed epoxy matrix. Thickness and the number of layers of final layered structures are optimized by the iterative design procedure. In the paper some interesting example of mimic optimization are shown. The numerical finite element method analysis complete the electromagnetic discussion showing how each layer of the optimized layered structures takes part in the final goal of mimicking the target electromagnetic profile.
