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
