Abstract :
A Pareto genetic algorithm is used to explore the performance of planar absorbers incorporating a sheet of periodic resistive patches embedded in a primary material substrate. The absorbing performance of a single-layer electric radar absorbing material (eRAM) with periodic resistive patches is compared to that of standard dual-layer absorbers made of wax laid on top of eRAM or magnetic radar absorbing material (mag- RAM).
