*TienYang Lo¹, Shunsuke Murai¹, Katsuhisa Tanaka¹ (1. Kyoto University)

In this study, we experimentally and numerically elucidated the optical properties of a bilayer metasurface system exhibiting out-of-plane quadrupole resonance characteristics and demonstrated the potential for bilayer metasurfaces system in directional light source applications.
