An unstructured-PEEC method for modelling electromagnetic thin region is proposed. Two coupled circuits representations are used for solving both electric and/or magnetic effects in thin regions discretized by a finite element surface mesh. Dynamic effects across the sheet are modeled by equivalent complex conductivity and reluctivity. Non simply connected regions are treated with fundamental branch independent loop matrixes coming from the circuit representation. The formulation enables the computation of eddy current losses and can be coupled with external circuits, PEEC-1D cables or coil thanks to the circuit representation
