Engineering Nearest Neighbor Coupling in Huygens Metasurfaces
conference on lasers and electro optics(2021)
摘要
Nearest neighbor coupling in antenna systems tends to reduce the overall optical efficiency of the system. Here, we compare arrays of disc and donut resonators that confine the impinging beam locally. Maximum optical efficiency of 70% for anomalous refraction is achieved.
