We present four designs of actively tunable micro-electro-mechanical system-based racetrack-shaped metamaterials (RSMs), which are denoted as RSM_1, RSM_2, RSM_3, and RSM_4, respectively. RSM_1 is composed of asymmetrically single RSM, while RSM_2, RSM_3, and RSM_4 are all composed of asymmetrically...
