Abstract :
A metamaterial reflector antenna is designed for robustness under high-power operating conditions by synthesizing pixelized metasurface geometries with minimized maximum field enhancement factor (MFEF) using a binary genetic algorithm (GA) stochastic optimizer. A metric is also included in the optimization to select unit cell geometries that share a high similarity among one another in order to improve the reflecting properties of the metasurface.
