Abstract
In this short paper, we present a theoretical study of a new probe for Nuclear Magnetic Resonance (NMR) microscopy, based on high-permittivity and low-loss ceramic resonators. The probe design consists of two coupled annular resonators, with a maximum of axial magnetic field within them. An analytical study of the first transverse electric (TE) eigenmode of a single resonator was undertaken to assess the reliability of the magnetic field distribution for NMR imaging purposes. The developed analytical model also enabled to study coupling between resonators as a tool for tuning the probe at the Larmor frequency.
