The integration of surface coils and metamaterials presents a promising approach for enhancing the performance of Magnetic Resonance Imaging (MRI) systems. This combination offers substantial benefits in terms of local staging flexibility, allowing for improved imaging capabilities in specific region of interest. However, due to the coupling between the two, low signal-to-noise ratio (SNR) and low contrast resolution further prevent the future development of clinical MRI. In this paper, we propose a conformal metasurface decoupling isolator for magnetic field enhancement in 1.5T surface coil MRI systems. We use conformal optical theory and polarization conversion mechanisms to eliminate the coupling between metamaterial and radio frequency surface coil. In addition, the conformal theory can be applied to the analysis of any surface boundary condition, providing an effective method for the design of magnetic resonance metamaterials. Through conformal optical analysis, portable metasurface designs can be achieved, opening up a promising avenue for easy-to-use surface-coil MRI scanners.
