摘要：

We address the question of the optimization of the performance of microwave absorbers. Our approach first use an optimization algorithm applied to a one-dimensional (1D) homogenized equivalent structure. The optimization yields a refractive index profile which is then used to build a 3D curved pyramidal structure. The validity of this approach is then verified through full-wave 3D numerical simulations. We address two type of questions: optimization of the shape for a given refractive index and optimization of material properties. (c) 2012 Wiley Periodicals, Inc.
