Abstract :
A thin phase-shifting surface is described that consists of three metallic and two dielectric layers. The metallic layers consist of conducting shapes, which are tuned to introduce the desired phase shift on an incident wave, while maintaining a very high amplitude of transmission coefficient. Such a quasi-transparent surface is then applied to phase-correcting devices and their operation validated experimentally.
