Surface and Volumetric Modes of Resonators Based on Periodic Wires for MRI Applications

In this work we demonstrate that periodic arrays of thin metal wires properly interconnected with lumped capacities can serve as combined surface and volumetric resonators of inductively-coupled radiofrequency coils for MRI. We investigate the surface and volumetric fundamental eigenmodes of a novel resonator formed by two parallel arrays of capacitively-loaded wires in terms of their magnetic field distributions. The proposed resonator can be used in coils for clinical and research MRI.
