Flexible and compact hybrid metasurfaces for enhanced ultra high field in vivo magnetic resonance imaging

Abstract Developments in metamaterials and related structures such as metasurfaces have opened up new possibilities in designing materials and devices with unique properties. Here we report a new hybrid metasurface structure, comprising a two-dimensional metamaterial surface and a very high permitti...
