The design of wideband, multilayer radar absorbing materials involves the solution an N-dimensional optimisation problem. Genetic algorithms appear to offer significant advantages over conventional techniques for this type problem owing their robustness and independence performance function derivatives. To illustrate use, paper considers two problems: first optimum multilayer, passive Jaumann absorbers with or without outer high-permittivity skin; secondly, examination potential such when configured as active i.e. frequency agile, dynamic structures.
