In Magnetic Resonance Microscopy (MRM), losses inherent to the probe and its interactions with the sample fundamentally limit the achievable Signal-to-Noise Ratio (SNR) and hence the spatial resolution. The reference volumetric probe for MRM is the solenoid, for which the performance is intrinsically limited by the electric field induced in the sample [1]. Here, we show that high permittivity ceramic ring resonators can overcome this limitation.
