0D / Port Impedance
Result Templates Template Based Post Processing
This template allows to calculate/read out several port properties:
The real part of the propagation constant gamma, alpha,
which describes the attenuation. The imaginary part of the propagation constant gamma,
beta, also called the (angular) wavenumber. Result will be zero for evanescent
waves. The port cutoff frequency. Result will be zero for modes
without cutoff, such as TEM. The port impedance. There are different impedance calculation
methods available for waveguide ports, such as UI, PI and PU-method:
P/I: Z = P / I^2
P/U: Z = U^2
/ P
U/I: Z = U /
I

Line Impedance from MWS (Wave Impedance if Line Impedance is zero)
For true TEM modes, all four results are
identical. For inhomogeneous structures and so called Quasi TEM modes,
the results differ. The voltage value U is integrated from the tangential
electric field along an open curve, which has to be selected. The current
value I is integrated from the magnetic field H along a closed curve,
which has to be selected. The curves need to be defined before starting
the macro.
OK
This button completes the setup of the template.
The new entry will be added to the list of templates which are executed
automatically after each run. The default name of the template is set
according to the settings, as long the name has not been changed manually.
Cancel
Aborts the setup of the template and closes
this dialog box without performing any further action.
