Dense and Sharp Resonance Peaks in Stretched Moiré Waveguides
G. Alagappan, C. E. Png
In this article, we demonstrate dense resonant peaks in the transmission spectra of a rectangular waveguide inscribed with a stretched moiré pattern. We investigated an array of si…

Fabry-Perot Resonance of Bilayer Metasurfaces
G. Alagappan, F. J. Garcia-Vidal, C. E. Png
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 accu…
