A lossy dielectric whose dielectric constant and loss tangent are 10 and 0.6 respectively is applied in the waveguide of calibration probe in order to simulate the influence of electric and magnetic field caused by the input and output coupling loop in the testing probe. The identical distribution of electric and magnetic field between testing probe and calibration probe is achieved. The application of lossy dielectric in the waveguide is capable of maintaining the symmetry between testing probe and calibration probe while the testing probe has moderate coupling and reduce the measurement error caused by low coupling of testing probe in the early device of image method.
