Abstract

The design of a frequency selective surface usually involves several aspects, as the geometry of the array element, the thickness of the substrate and the incidence angle, which must be adequately defined so that the multiple requirements for the specific task are fulfilled. In this work, we investigate the application of a multiobjective approach to the design of a microwave absorber in the X-band, considering the simultaneous optimization of the bandwidth and the attenuation in the chosen frequency band. The obtained results encourage the use of this approach, as the algorithm was capable of finding adequate trade-offs between the objectives.
