Travelling wave magnetic resonance imaging (twMRI) offers to overcome the inhomogeneities due to the standing wave patterns, and the use of coil arrays with multiple coil elements. The excitation of the spins have been commonly done with RF surface coils, dipole and patch antennas, etc. The resonant device should be able to generate an adequate magnetic field to transmit the signal to a distant object using a waveguide. In this paper, we numerically simulated the magnetic field of the principal mode (TM0) as a function of the driving voltage phase.
