An Inductive Resonator for the Head is described using Transmission Line Segments for strong inductive coupling of the mesh elements. A circuit analysis is presented that provides a means for tuning the resonator at high field (7T). The resonator exhibits a strongly coupled high-pass mode distribution with capacitors located only in the legs or cross-members of the coil. The virtual grounds of these segments and the distributed capacitance of cross-members minimize Electric fields.
