cst studio suite microwave studio

Hi,

In CST microwave studio. Regarding the ports. What is the difference between line impedance and wave impedance.

Thanks

Which version of CST studio you are using? Use HFSS for microwave simulation.

The line impedance (characteristic impedance) of a uniform transmission line, is the ratio of the amplitudes of a single pair of voltage and current waves propagating along the line in the absence of reflections.

The wave impedance of an electromagnetic wave is the ratio of the transverse components of the electric and magnetic fields (the transverse components being those at right angles to the direction of propagation). For a transverse-electric-magnetic (TEM) plane wave traveling through a homogeneous medium, the wave impedance is everywhere equal to the intrinsic impedance of the medium.
