Pareto-optimal design of broadband microwave absorbers using genetic algorithms

The authors illustrate the application of multicriteria optimization technique to the synthesis of broadband microwave absorptive coatings. For many applications, the problem of designing a coating involves a tradeoff between conflicting goals, namely those of minimizing the total coating thickness while achieving maximum absorption. The authors propose a continuation of the work of Michielssen et al. (in press), by incorporating, within the genetic algorithm, a mechanism for investigating the tradeoff between coating thickness and absorption, by using the concepts of Pareto-optimality. Numerical results are presented.<>
