Reconfigurable and Tunable Metamaterials: A Review of the Theory and Applications

(a) Configuration of TM mode reconfigurable cloak; independent control over the effective material properties of each unit cell within the cylindrical region is achieved through independent biasing of each column of diodes. (b) Magnetic field distributions surrounding and within the dielectric cylinder with and without the cloak shell at 9.5 GHz. The material properties throughout the structure may be tuned to act as a cloak around the inner cylinder. Used by permission [41].
