Abstract :
A general method is reported for measurement of the complex reflection and transmission coefficients of a two-port device by connecting it between a reflectometer and a sequentially mismatched detector. The coefficients are determined from the ratios of outputs from two power sensors to that of a third, so that the method may be of use for adapting a scalar network analyser for measuring complex quantities. Experimental results from a waveguide WG22 implementation are described.
