“…Indeed, the α configuration can be seen as a special β one with no core, which actually means that p is equal to 1 (because χ 2 = 1 − χ 1 ). Since Φ and Φ III are equal to 1 in that case, the EC loss density for α configuration can be recovered, leading to the equations given in (12).…”

“…SMCs are traditionally manufactured by powder metallurgy [5][6][7]. Research interests mainly focus on composite modelings [8][9][10][11][12][13][14][15] for the effective permeability and eddy current losses. Efforts are continued on the delicate treatment in powder coating or searching new powder alloy or insulation layer so as to enhance the properties [16,17].…”

Soft magnetic composites (SMCs) possess promising electromagnetic characteristics and attract intense research and application interest in the engineering community. Fabrication of composites with customized architecture is feasible due to the recent advances in additive manufacturing (AM) techniques. The systematic progress of computational optimization has opened up the possibility of devising such structures. This article presents newly structured SMCs which can recently be possible by AM. The effective permeability and eddy current losses are studied in comparison to those properties of traditionally fabricated SMCs. With this hollow inclusion arrangement, for the same iron volume fraction, the effective permeability can be greatly enhanced (more than tenfold) while the eddy current losses decrease considerably. For the same magnetic property, we save iron material, make the composite lighter, and benefit from a lower level of eddy current losses with the hollow configuration.
