Abstract

Exploiting moiré interference, we make a new type of reconfigurable metamaterials and study their transmission tunability for incident electromagnetic waves. The moiré pattern is formed by overlapping two transparent layers, each of which has a periodic metallic pattern, and the cluster size of the resulting moiré pattern can be varied by changing the relative superposition angle of the two layers. In our reconfigurable metamaterials, both the size and structural shape of the unit cell can be varied simultaneously through moiré interference. We show that the transmission of electromagnetic waves can be controlled from 90% to 10% at 11 GHz by experiments and numerical simulation. The reconfigurable metamaterial proposed here can be applied in bandpass filters and tunable modulation devices.

Fig. 1
Fig. 1 Schematic view of two-layer superposition with periodic structure of metallic disks (radius of the disk: 1.2mm, unit cell: 3mm) for various rotation angles: (a) θ = 0°, (b) θ = 15°, (c) θ = 20°, (d) θ = 30°, (e) θ = 40°, (f) θ = 45° (see Visualization 1).
Fig. 2
Fig. 2 Simulation results of transmission properties of the reconfigurable metamaterial based on moiré interferences: Schematic view of unit-cell structures for various rotation angles (a) 0 (case 1) (b) 2 × sin 1 ( 1 / 10 ) (case2), and (c) 2 × sin 1 ( 1 / 26 ) (case 3), (d) Simulated transmission spectra in case 1 (black line), case 2 (red line) and case 3 (blue line), (e) Surface current density plots in the meta-atom at resonance frequencies (I) in case 2 (at 27 GHz), (II) in case 3 (at 11 GHz), and (III) in case 3 (at 17 GHz). (The arrows indicate the directions of the surface currents and the red color means high intensity region of electric field.)
