The automatized computer workbench for complex multi-frequency measurement at the 5 millimeter wave band

To carry out the electromagnetic super-high frequency diagnostics of dielectrics on a base of the inverse problem solution it is necessary to provide the automated high-precision measurement of the complex reflection factor (CRF) for electromagnetic field at a set of frequencies. From this point of view the methods of bridge-scheme measurements have some advantages: the competitive simplicity of the bridge construction and measurement scheme, easy calibration, wide frequency range, measurement's high precision, which in principia depends only from the precision of the calibrated loading. The structure of the automated workbench for multi-frequency measurements of CRF in SHF wave band is considered. The method for CRF measurement with employing of circuit model is proposed. That allows to automate the measurements and avoid the procedure of the joint balancing.
