However, a majority of demonstrated metasurface structures possess fixed properties, e.g. fixed operational bandwidth or functionality. An active control of metasurface functionalities and bandwidth is highly desirable for engineering an advanced electromagnetic and photonic devices. Here, we suggest and demonstrate experimentally a novel type of metasurface capable of dramatic enhancing the image quality.This work was supported by Russian Science Foundation (Project No. 15-19-20054).2enPublisher Copyright: © 2017 IEEE.MetasurfacesMRITunable metamaterials2017-10-1810.1109/APUSNCURSINRSM.2017.807279185042278370
