This paper presents an innovative approach based on the partial element equivalent circuit (PEEC) method and the analytical integration of its coupling equations.. Emphasis is placed on the implementation of a surface-based formalism, referred to here as S-PEEC (surface-PEEC). The theoretical principles are explained and confirmed by experimental tests on a planar mock-up. To showcase the versatility of the numerical model, various configurations—including different positions, materials, and calculation domains—are explored. A comprehensive description of the experimental setup is provided, followed by a comparison between the measured current distributions and those obtained through simulations using the S-PEEC formulation, which validates the proposed methodology.
