Bio-inspired optimization techniques for the design of millimeter wave antireflective surfaces

This paper presents the successful application of bio-inspired optimization algorithms to electromagnetics problems. The problem considered is the design of antireflective surfaces using sub-wavelength gratings periodically created inside the substrate. We apply the rigorous coupled wave analysis to model the reflection and transmission properties of the material and utilize bio-inspired optimization methods such as the particle swarm optimization and ant colony optimization to determine the optimal parameters that achieve the desired performance.
