Most high field imaging coils are based on lumped elements and copper strips or transmission line elements. Recently an alternative design was presented using dipole antennas mounted on high permittivity non-resonant ceramic blocks in order to force the penetrating wave into the far field region. In this current work a new concept is presented which uses unilaterally shielded high permittivity ceramic discs which, when coupled to the body, are designed to resonate in the TE01 mode.
