Summary:
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.
