Physics · Electromagnetic Waves and Transmission Lines
Scattering parameters (S-parameters) are more suited than impedance parameters (Z-parameters) to describe a waveguide junction because:
- 1Scattering parameters are directly measurable at high frequencies but impedance parameters are not✓
- 2Impedance parameters vary over unacceptably wide ranges
- 3The scattering matrix is always unitary
- 4The scattering parameters are frequency invariant whereas the impedance parameters are not
Correct answer
Scattering parameters are directly measurable at high frequencies but impedance parameters are not
