  • Abstract
    More than 110 dB isolation is experimentally realized in a narrow band in this work. Multiple varactors based tunable metamaterials were placed between two co-polarized monopole antennas. The metamaterials are controlled using an genetic algorithm (GA) based optimization program. The optimization goal is to minimize the transmission coefficient of a. After 3000 generations of evolution, more than 110 dB isolation ratio is achieved. This method is verified by two experiments with different metamaterial structures.
