Pixelated Metamaterial Determination Using Genetic Algorithm and HFSS/Matlab Integration

A pixelated metamaterial was designed using a genetic algorithm (GA) to match the reflection coefficient to that of a Gap Ring Resonator structure. The significance of this is that a GA can be used to arbitrarily meet design a goal without one knowing the priori of the physical metamaterial structure. The pixel mapping was controlled by interfacing Matlab with HFSS. Using the full wave simulation power of HFSS, s-parameters were exported to feed into an optimization cost function. Completion of hundreds of simulations led to the final pixel mapping that closely matched the response of the Gap Ring resonator across a wide frequency range.
