This study demonstrates the formation of Dirac cone using double-layer ring dipole arrays (RDAs) and proposes a method for dynamically controlling the band gap. It is found that the Dirac cone appears at the optimum separation in double-layer RDAs and the band gap can be formed and controlled by decreasing the separation between the two layers. This research has significant implications for the development of new applications for artificial electronic materials.
Dirac cone formation and a method for dynamically controlling the band gap using double-layer ring dipole arrays (RDAs) are demonstrated and proposed. The design is mainly based on the composite righthanded-left-handed circuit theorem. It is theoretically and analytically confirmed that the Dirac cone appears at the optimum separation in double-layer RDAs, which are known to have surface-wave modes in the case of a single-layer RDA. It is also found that the band gap can be formed and controlled by decreasing the separation between the two layers. The Dirac cone formation and its dynamic control method on the artificial structure will open the possibility of new transistor applications as an artificial electronic material showing the properties of Dirac half-metals.
