Electromagnetic absorbers are elements designed to avoid (or at least reduce) reflection of electromagnetic energy in a given frequency band, which could otherwise be harmful to living beings, or simply cause interference with other electronic equipment. Thus, this article presents the results achieved by using a metaheuristic for optimizing their design in the frequency range of wireless communications, ie, between 0.8 and 1.9 GHz. In this case, the algorithm proposed by Formato in 2007, ie, Central Force Optimization (CFO), was used
