Abstract
Abstract
Metasurface opens a gateway to manipulate electromagnetic properties by establishing various resonance modes. But the vast majority of metasurface resonance modes are statically adjustable. In this work, the vanadium dioxide is introduced into a mirror-symmetric double-splitting semicircle ring resonator to constitute a tunable metasurface mode switch between the Fano resonance and Breit–Wigner resonance, which is controlled by two external temperatures. The numerical simulation results show that the proposed metasurface expresses the Fano resonance around 1258 nm when the temperatures are T
1 = 27 °C and T
2 = 82 °C. When T
1 = T
2 = 27 °C or 82 °C, the Breit–Wigner resonance mode can be excited near 1100 nm. This mode switch behavior can be well understood with the surface current distribution and multipole electromagnetic decomposition.
