Abstract

Metasurfaces are well known for their functionality to control the reflection and refraction of waves via the introduction of subwavelength units along the surface. The efficiency is an important issue for enhancing metasurface functionalities. High efficiency metasurfaces in the transmission geometry have been recently designed by using various approaches including Huygen’s surface, etc. However, there are still severe limits in the present approaches. In this work, we demonstrate new mechanisms to realize transparent metasurfaces, leading to unprecedented new functionalities beyond current techniques. These advances in fundamental physics may also have important implications in practical applications.
