# skrf.media.freespace.Freespace.theta_2_d¶

Freespace.theta_2_d(theta, deg=True, bc=True)

Convert electrical length to physical distance.

The electrical length is given by $$d=\theta/\beta$$.

The given electrical length can be given either at the center frequency or on the entire band depending of the parameter bc.

Parameters
• theta (number) – electrical length, at band center (see deg for unit)

• deg (Boolean, optional) – is theta in degrees? Default is True (theta is assumed in degrees)

• bc (bool, optional.) – evaluate only at band center, or across the entire band? Default is True (evaluation assumed at band center)

Returns

d – physical distance in meters

Return type

number, array-like
