Layout of the ADSR unit cell.
Simulated transmission through a symmetric double split resonator (SSR), an asymmetric double split resonator (ASR), and the proposed ADSR.
Simulated and measured magnitude (a) and phase (b) of the ADSR transmission response. Three resonances are found at 300, 509, and 717 GHz, respectively. The inset shows a photograph of the fabricated metasurface.
Current distributions at the three resonances. The asymmetric current components are shown in dark blue while the dipole currents are displayed in light red.
Q-factors observed for the current trapped mode in the ADSR and the ASR for a sweep of the asymmetry angle from 10° to 60°.
