Optimum geometry for planar structures regarding their loss factor

Planar structures are often used recently due to their many advantages. Transformers, power inductors and EMI filters are only a few components that are constructed using this technique. In order to increase their efficiency, parasitic capacitance (EPC) and equivalent series inductance (ESL) must be decreased and HF losses must be appropriate to their utilization. This paper represents a study which aims at finding how the shifting of the windings influences HF losses and also determining the optimum geometry for increasing the losses in planar structures.
