description A transportation system 100 includes a ground station 102 configured to modulate 116 an unmodulated message signal 112 with a first-phase of a three-phase stator excitation to create a modulated stator excitation. A stator is coupled to the ground station 102, the stator including a coil assembly, wherein the coil assembly of the stator is configured to receive the modulated stator excitation 118 from the ground station by the coupling. The coil assembly generates a travelling magnetic field in response to receiving the modulated stator excitation 118. A vehicle 106 includes a rotor 108, wherein an eddy current is induced by the rotor in response to the travelling magnetic field, wherein the eddy current corresponds to the modulated stator excitation 118. The eddy current induces a secondary magnetic field opposing the traveling magnetic field, the secondary magnetic field causing the rotor and the vehicle 108 to translate relative to the stator 104. The vehicle 106 is configured to determine a demodulated message signal corresponding to the unmodulated message signal 112 based on the eddy current.
