skrf.tlineFunctions.electrical_length_2_distance(theta, gamma, f0, deg=True)[source]

Convert electrical length to a physical distance.

$d = \frac{\theta}{\gamma(f_0)}$
Parameters
• theta (number or array-like) – electrical length. units depend on deg option

• gamma (number, array-like or function) – propagation constant. See Notes. If passed as a function, takes frequency in Hz as a sole argument.

• f0 (number or array-like) – frequency at which to calculate gamma

• deg (Boolean) – return in degrees or not.

Returns

d – physical distance in m

Return type

number or array-like (real)

Note

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