Design of microwave broadband absorbers using a self-adaptive differential evolution algorithm

Abstract

Microwave broadband absorber design for a desired frequency and angle range is presented. The design technique is based on a self-adaptive Differential Evolution (DE) algorithm. Numerical examples are compared with the existing in the literature and with those found by the other evolutionary algorithms. The results show that the new DE algorithm version outerperforms other global optimizers like Particle swarm optimization (PSO) variants and the classical DE algorithm. © 2008 Wiley Periodicals, Inc.
