Two-detector method of wave length determination in metaldielectric waveguide

The method of determination of a wave length in a metaldielectric waveguide, based on the analysis of results of signal measurement of power-level detectors, launched by traversal and longitudinal slots has been developed. The slots centres are located on known distance from the waveguide end, the phase shift between tapped off waves is 90° on any frequency of waveguide gamut, and signals from detectors are measured at consecutive connection of a matched load and the short-circuiter.
