skrf.media.freespace.Freespace.mu
- property Freespace.mu: Number | Sequence[Number] | ndarray
Complex dielectric permeability.
If \(\tan\delta_m\) is not defined:
\[\mu = \mu_0 \mu_r\]otherwise,
\[\mu = \mu_0 \Re[\mu_r] (1 - j\tan\delta_m)\]where \(\tan\delta_m\) is the magnetic loss tangent.
- Returns:
mu – Complex permeability in H/m.
- Return type:
number
