skrf.tlineFunctions.surface_resistivity¶
- skrf.tlineFunctions.surface_resistivity(f, rho, mu_r)[source]¶
Surface resistivity.
The surface resistivity is calculated as:
\[\frac{ \rho }{ \delta }\]where \(\delta\) is the skin depth from
skin_depth().See www.microwaves101.com [1] or wikipedia [2] for more info.
- Parameters:
f (number or array-like) – frequency, in Hz
rho (number or array-like) – bulk resistivity of material, in ohm*m
mu_r (number or array-like) – relative permeability of material
- Returns:
surface resistivity – Surface resistivity in ohms/square
- Return type:
number of array-like
