Fabry-Perot Resonance of Bilayer Metasurfaces

, 2023
In this study, we constructed a Fabry-Perot cavity with nanostructured, thin resonant metasurfaces as meta-mirrors. We developed a temporal coupled-mode theory and provided an accurate generalization of Fabry-Perot resonance and analytically derived the transmission characteristics.
