Abstract :
It is shown that the cross-ratio method of reflection correction is applicable also to waveguides at millimeter waves when precision waveguide sections of well defined cross dimensions are used as reference air-line impedance standards. The uncertainty is small as the dimensions of the waveguides used are determined with low uncertainties.
