In this paper, wave interaction with a ferrite material in a rectangular waveguide system is analyzed by using the transmission line (TL) model at Ku band. Using the presented model, the equivalent transverse admittance of the system is extracted. According to the corresponding relationship between the transverse admittance and the scattering parameters (S11, S21) of the system, the saturation magnetization and permittivity of a ferrite material (4πMs and
ɛ
r) are extracted. In comparison to other works, the proposed method has made the implementation very easy and has eliminated the problems associated with phase measurement and calibration. The presented model is simulated on the several types of ferrites and experimentally is tested on an SL‐470 ferrite sample. Comparison of the results shows that the extracted parameters are close to the manufacturing values with %5 error.
