In this paper, numerical calibration method is proposed in full wave simulator for characterization of
substrate integrated waveguide in terms of propagation constant and characteristic impedance. The principle and
derivation of formulas are systematically described to extract these two guided-wave parameters. Numerical results
in comparison with analytical solutions of classical rectangular waveguide verify the proposed method.
