"Meta-atomless" architecture based on an irregular continuous fabric of coupling-tuned identical nanopillars enables highly efficient and achromatic metasurfaces by Yaǧcl, H. Bilge, Demir, Hilmi Volkan

“…Although the use of near-field coupling for tuning electromagnetic resonances found its use in constructing efficient narrow-band designs, such structures fell short of providing high efficiency over a broad spectrum. Here, we propose and show that tightly packed fabrics of identical dielectric nanopillar waveguides with continuously tuned intercoupling distances make excellent and complete achromatic metasurface elements. …”
