Are "L and Pi matching networks" reciprocal networks?

I would like to know if "L and Pi matching network" that are used for impedance matching are reciprocal networks?

It looks to me as if they are reciprocal in the case of impedance matching.

Thanks in advance.

I think they are not such like resiprocals they are compensators.
As it contains two capacitors and one inductor or vice versa in case of pi they juct store enrgy and try to match impedance by increasing and decreasing energy.

Match range – determined by plasma impedance range. Usually
determined empirically. One can use existing matches or design its
own box with variable components. Use this matches to manually
tune in to plasma condition. Plasma impedance can be determined
two ways:
– Load the input of your box with a 50 ohm load and measure the
impedance on the match output.
– Measure the values of the series
