The experiments presented in the paper reflect the macroscopic anisotropy of the material, which is deliberately strong for the Fe-Si GO strips and must not be neglected in the case of Fe-Si NO strips.
The paper refers to a new direction in studying macroscopic anisotropy by making use of simpler measurement methods with strong impact in practical applications linked to a new and more efficient design of electrical machines.
Macroscopic anisotropy and micro-inhomogeneity are thus fundamental properties of all polycrystalline materials.
It is well known that the shape of cells in the islands-sea structure causes the macroscopic anisotropy of the dielectric constant even if both the islands and the sea are isotropic by themselves.
The dimensional stability of plastic foams like polystyrene foam can be estimated from the shape of cells, which is expressed by the macroscopic anisotropy of the dielectric constant.
This is due to the bilayer structure designed to cancel the macroscopic anisotropy with respect to the axial and transverse directions.
