6.2.8   Below cutoff calculations

QuickWave enables below cutoff frequency calculations for the following parameters and quantities:

• S-parameters

• Complex wave impedance of transmission line

• Complex propagation constant in transmission line

• Power Balance

• SWR and group delay

More discussion about interpretation of the S-parameters below cutoff can be found in ref. [44].

A discussion concerning the below cutoff calculations is presented in User Guide 3D: Advanced S-parameter problems for waveguide-to-coax example.
