Calculating the PV Impedance
The Zpv impedance is the impedance calculated from values of power (P) and voltage (V):
| 
| (1) |
where the power and voltage are computed directly from the simulated fields.
The power is computed in the same way as the Zpi impedance. The voltage is computed as follows:
| 
| (2) |
The result over which HFSS integrates is referred to as the impedance line — which is defined when the ports are set up. To define the impedance line for a port, select the two points across which the maximum voltage difference occurs. You must define an integration line to specify where the maximum voltage difference will be.
