All-pass metasurfaces based on interconnected dielectric resonators as a spatial phaser for real-time analog signal processing

A spatial phaser based on all-pass metasurfaces using Interconnected dielectric resonators is proposed for real-time-analog signal processing (R-ASP). The structure is simple to fabricate and is constructed from a single dielectric layer using standard laser hole drilling processing. Its all-pass transmission response along with its transmission delay characteristics are also demonstrated using rigorous coupled-wave analysis (RCWA).
