A method to find the optimum permittivity of the dielectric pads that maximizes the matching by analyzing with a simple 1D analytical model the near field wave impedance of the fields generated by a magnetic loop which propagate through different materials. The permittivity values that maximize the matching in this simplified model are compared with the permittivity values that maximize the B1 field in 3D simulations to investigate the correlation between matching and high permittivity dielectric pads.
