Dual tuned (DT) coplanar and concentric Radio Frequency (RF) coils, tuned at the resonance frequencies of hydrogen (1H) and sodium (23Na), are a valid way to coregister anatomical and physiological information in Magnetic Resonance Imaging. In this common solution, the high mutual coupling between the coils causes a shift in the resonancedesired frequencies. We propose an innovate strategy for decoupling coils by employing coplanar distributed magnetic traps (DMT), designed to work in maximum coupling condition, i.e. the simultaneous conjugate matching of the feeding ports.
