Mutual coupling is a long-standing and critical issue that affects the performance of parallel transmit arrays. Here, we implement a frequency selective surface method to decouple array elements that helps realize the benefits of RF shimming and pulse shaping algorithms, while also increasing array transmit efficiency.
