3.15 Ferrite

Ferrite denotes a ferrite medium magnetised with a static z-oriented magnetic field.

It has all the parameters of dielectric isotropic, which are directly applied to all three components of relative permittivity and conductivity, and to z-component of relative permeability and magnetic loss. Additionally the ferrite model has three parameters describing its gyrotropic behaviour: damping constant alfa [unitless], saturation magnetisation Ms [T] and static biasing z-directed magnetic field Hi [A/m]. These are used to obtaind effective values of x- and y- components of permeability, magnetic loss, and in-plane coupling. Details about the model and its implementation are discussed in references [90] [104] in User Guide 3D: Bibliography chapter.

It is advised to refer to Ferrite for more information.
