In this abstract we present a novel approach to simultaneously inductively decouple large coil arrays of identical parallel elements. The method utilizes a flux blocking pad to control the amount of mutual inductance between coils. The method was successfully tested and implemented in decoupling two elements and was then extended to a 7-element array. Decoupling measurements greater than 20dB have been demonstrated between neighboring elements. The method is simple and elegant and can easily be extended to accommodate large numbers of array elements.
