ABSTRACT:
The present invention relates to the variable wave impedance generator (VWIF) which is used for the electric field intensity measuring instructor calibration, the magnetic field intensity measuring instructor calibration, the antenna calibration, and the unnecessary electronic wave interference and tolerance (EMI/EMS) measurement of the electric and electronic equipment using the features to generate the low impedance electronic wave (or, magnetic field) at the point meeting in phase, and the high impedance electronic wave (or electric wave) at the point meeting out of phase, when the power transmits in the coupled transmission line inside in the opposite direction from each other.
