Ultrathin capacitive metasurfaces, comprising nonresonant metal strips or patches , are shown to cause exceptionally large phase discontinuity of incoming light. The strong electric response in metasurfaces leading to phase discontinuity is demonstrated experimentally and characterized using effective medium theory. Without needing resonant optical scatterers, these metasurfaces enable deep subwavelength planar photonics.
