Design of an optimal multilayer electromagnetic absorber through Spiral Algorithm

Edgar García, Ivan Amaya, Rodrigo Correa

Abstract


This article presents a strategy for the design of an optimal planar electromagnetic absorbers of several layers. The electromagnetic absorbers designed can operate in different frequency ranges and were optimized by using the well-known spiral optimization algorithm. Results for the case of three, five, seven and nine layers, showed the advantage of using this algorithm mainly in terms of fewer adjustable parameters and its great capacity for intensification and diversification. The results obtained were compared to those reported with other optimization methods.


Keywords


Electromagnetic absorbers; optimization; spiral optimization; metaheuristic algorithms; Pareto analysis.
