skrf.tlineFunctions.skin_depth¶
- skrf.tlineFunctions.skin_depth(f, rho, mu_r)[source]¶
Skin depth for a material.
The skin depth is calculated as:
\[\delta = \sqrt{\frac{ \rho }{ \pi f \mu_r \mu_0 }}\]See www.microwaves101.com 1 or wikipedia 2 for more info.
- Parameters
f (number or array-like) – frequency, in Hz
rho (number of array-like) – bulk resistivity of material, in ohm*m
mu_r (number or array-like) – relative permeability of material
- Returns
skin depth – the skin depth, in meter
- Return type
number or array-like
