Dimer Dielectric Huygens' Metasurface: Realizing Perfect Anomalous Reflection at 60 GHz

This paper reports a coarsely discretized dielectric Huygens' reflective metasurface featuring two meta-atoms known as meta-dimer per metasurface period. We termed the resulting metasurface as dimer dielectric Huygens' metasurface (Di-DHMS). The coarse discretization dramatically simplifies the design and reduces mutual coupling effects, leading to a cost-effective, robust, and highly efficient metasurface design. Through full-wave simulations at 60 GHz, we demonstrate that the proposed Di-DHMS can achieve perfect anomalous reflection for the oblique plane wave incidence.
