1. A resonator device for a magnetic resonance system, the resonator device comprising:

  • a resonator body comprising a periodic arrangement of a plurality of cells about a central interior region, each cell comprising a dielectric substrate and thin-film conductors disposed on the dielectric substrate;

    wherein the plurality of cells forms lateral faces of the resonator body, and the thin-film conductors in each respective cell form;

    a leg element comprising an elongate leg element conductor, wherein the leg element extends in a longitudinal direction parallel to the largest dimension of the central interior region of the resonator body,a first ring element comprising a first elongate ring element conductor, wherein the first ring element extends perpendicular to the leg element, anda second ring element comprising a second elongate ring element conductor, wherein the second ring element extends perpendicular to the leg element,wherein the leg element extends from a central portion of the first ring element, along a center of the lateral face formed by the respective cell, to a central portion of the second ring element; and

    the periodic arrangement of the plurality of cells defining a periodic network of inductive and capacitive elements adapted to produce a magnetic field in the central interior region.
