1. A spark gap device, comprising:
a first planar coil, defining an axis normal to a coil plane and defining a first aperture substantially centered about the axis;
a second planar coil, offset from the first planar coil along the axis and substantially parallel to the coil plane, the second planar coil defining a second aperture substantially centered about the axis;
a first substrate, thermally coupled with the first planar coil and electrically isolated from the first planar coil;
a second substrate, thermally coupled with the second planar coil and electrically isolated from the second planar coil; and
a conductive element disposed in the first aperture and substantially aligned with the axis.
