Abstract: High Q-value radio frequency (RF] coils are described. In general, the RF coils include multiple conductor layers that at least partially overlap to define a capacitive region that equalizes current flowing in each conductor. In some instances, the RF coil includes sets of layered conductors, where each set of layered conductors overlaps in an overlap region. In some other instances, the RF coil includes a spiraled conductor coupled to a dielectric material, where the number of turns of the spiral defines the overlap area. Multiple spiraled conductors can be interleaved. An equalization coil can also be provided to equalize currents along an axial dimension of each conductor in such RF coils. The thickness of the conductors is less than three skin depths, and preferably less than one skin depth, to overcome skin-depth limitations.
