Abstract

The characterization of the energetic magnetic behavior of hysteretic materials and the determination of the surface impedances are proposed. A numerical model in time domain is adopted for the calculations. The use of parallelogram-shaped hysteresis loops allows for simplifying the numerical formulation and for reducing the computation time with respect to more accurate models. Equivalent major loops have been defined starting from the measured ones. Comparison with the modified scalar Preisach model is presented and discussed.
