Highly localized electromagnetic waves appearing in subwavelength structures, such as plasmons lying at a metal surface, are fundamental ingredients in nanophotonics. Negative magnetic permeability metamaterials, already proposed for magnetic resonance imaging (MRI) applications, can also support surface plasmonic excitations. Here, we propose to exploit these phenomena to improve the MRI efficiency. We show that a negative magnetic permeability metamaterial slab, coupled to a surface coil, supports highly localized magnetic surface plasmons allowing to boost and to spatially manipulate the radio-frequency electromagnetic field with a great potential to enhance the coil signal-to-noise ratio with respect to the standard setup.
