Self-decoupled coils (SDCs) were recently described which can solve complex coupling issues in dense arrays. SDCs have a simple structure and represent a general approach. However, dipole mode in SDCs make it sensitive to the load. In this work, we introduced a differential mode to the design of SDCs to alter the necessary value of Cmode and a coils’ robustness to loading. This differential-mode SDC can be seen as a combination of differential-mode decoupling with self-decoupling. We found that suitable Cmode can choose to increase coil robustness as well as avoid added coil loss.
