Magnetic Modelling

The magnetic properties of the dielectric is defined.

Non-Magnetic

The relative permeability ( $μ_{r}$ ) is set to 1.0 and the magnetic loss tangent ( $\tan δ_{u}$ ) is set to 0.0.

Frequency Independent

The media is defined in terms of the relative permeability ( $μ_{r}$ ) and the magnetic loss tangent ( $\tan δ_{u}$ ).

The effective permeability of the dielectric is given by:

(1)

μ_{e f f} = μ_{0} μ_{r} (1 - j \tan δ_{μ})

Frequency List (Linear Interpolation)

The dielectric properties of the material are defined at various frequency points. Values for the dielectric properties are then linearly interpolated to obtain the dielectric properties at frequency points other than specified.

Data points at a range of frequencies are specified. Values for the dielectric properties are then linearly interpolated to obtain the dielectric properties at frequency points other than specified. Parameters required are frequency, relative permeability ( $μ_{r}$ ) and the magnetic loss tangent ( $\tan δ_{u}$ ).
