Przenikalność magnetyczna zespolona taśm anizotropowych

In the paper the frequency characteristics of complex permeability of amorphous material have been defined. The achieve this Polivanovs model has been used. Polivanov determined complex permeability by solving Laplace'a equation. Such a solution does not take into consideration skin effect. Therefore in the paper Helmholtz equation has been solved. Obtained results have been compared with Polivanovs ones.
