There is a similar simple approximation for a coplanar waveguide short-circuit, also given in [54]. The short circuit is inductive in nature.
The equivalent length extension associated with the
fringing fields is
Equation (12.29) is valid when the metalization thickness
does not become too large (
).
The short end inductance can be written in terms of the
inductance per unit length and the wave resistance.

According to W.J.Getsinger [55] the CPW short-circuit inductance per unit length can also be modeled by

based on his duality [56] theory.
