The
isolated meshes of the Inductive Resonator couple via strong mutual
inductance to develop a high-pass distribution of modes for the coil. While simple mutual inductive coupling of
neighboring meshes can accurately fit the modes of low frequency resonators,
this model does not work for the shielded 7T head coil. Here, a transmission line and distributed
impedance model is developed for the shielded 7T inductive resonator that
accurately describes its modes and provides a model for high-frequency
design.
