Enhancement of Magnetic Resonance Imaging with Metasurfaces

Abstract

It is revealed that the unique properties of ultrathin metasurface resonators can improve magnetic resonance imaging dramatically. A metasurface formed when an array of metallic wires is placed inside a scanner under the studied object and a substantial enhancement of the radio­frequency magnetic field is achieved by means of subwavelength manipulation with the metasurface, also allowing improved image resolution.
