**reactive power in waveguides**

Hallo,

scattering parameter description is the most common way to analyze microwave circuits. The forward and backward travelling power waves a,b are either defined as quantities, proportional to the real power of the travelling voltage,current v,i waves or as the real power of the travelling electromagnetic field waves E,H.

Phases from a,b are defined as the phase of v,i or E,H at an arbitrary starting point (time and place).

My question is, how to extract the REACTIVE POWER part on any port of a circuit.
