skrf.tlineFunctions.distance_2_electrical_length(gamma, f, d, deg=False)

Calculates the electrical length of a section of transmission line.

Parameters :

gamma : function

propagation constant function, which takes frequency in hz as a sole argument. see Notes.

l : number or array-like

length of line, in meters

f : number or array-like

frequency at which to calculate

deg : Boolean

return in degrees or not.

Returns :

theta : number or array-like

electrical length in radians or degrees, depending on value of deg.

Notes

the convention has been chosen that forward propagation is represented by the positive imaginary part of the value returned by the gamma function
