Current path possibilities in the case of rectangular double-loop (RDL) designs. Rectangular (a) double-layer (i.e., loops are in parallel and thus current flows in each one) and (b) double-turn (i.e., loops are in series and thus current flows in each one) coils are designed to obtain currents circulating in the same directions (RDL-SC and RDT-SC). Also, rectangular (c) double-layer and (d) double-turn coils are designed to obtain currents circulating in the opposite directions (RDL-OC and RDT-OC).
