Concurrent RF transmission and signal reception is significant for applications including imaging species with ultra short T2 values, and measurement of spin properties during excitation. In this study, magnetic field decoupling of 75dB between transmit coils and the receive coil is accomplished using a transmit array system. In order to detect concurrent MR signals, linearly polarized electromagnetic fields are utilized to generate a plane with zero perpendicular magnetic field components coplanar with the receiver coil.
