Use the Three-Port Network node to characterize the response of a three-port network system such as reflection and transmission using S-parameters.
A Three-Port Network can only be applied on boundaries that extend between two metallic boundaries — that is, boundaries where
Perfect Electric Conductor,
Impedance Boundary,
or
Transition Boundary conditions apply — separated by a distance much smaller than the wavelength.
Coaxial does not support nonzero azimuthal mode number. The
Azimuthal mode number in the
Physics interface should be defined as zero.
Matrix defines the S-parameter by a constant matrix input.
Touchstone file imports a three-port Touchstone file to characterize the three-port boundaries as a function of frequency.
Select Interpolation and
Extrapolation types to obtain S-parameter values from the imported Touchstone file corresponding to the simulation frequencies.
