Abstract

Embodiments of the invention are directed toward a crossed-loop electron paramagnetic resonance resonator comprising a first resonator having a first resonator axis; and a second resonator having a second resonator axis. The first resonator axis and the second resonator axis can be substantially perpendicular. Either or both the first resonator and the second resonator can be a ribbon resonator having a plurality of metallic ribbons formed in a loop. Each metallic ribbon can include a central axis. The plurality of metallic ribbons can be arranged parallel relative one to another.
