To provide a "body coil" for high-field MRI systems, FDTD simulation results of a novel travelling wave setup are shown, that used two coaxial modules. The setup is able to excite higher-order modes of wave propagation enclosed in a defined imaging area. While this creates diverse distributions of the transverse magnetic field for B1-shimming, the transmission efficiency remains inferior to resonant structures.
