Signal Flow Graph for Optimizing of Mutual Sensors Reflection in the Multiprobe Microwave Multimeter

The article presents evaluation of the influence of sensors number and mutual reflection on the measurement accuracy of the microwave multiprobe multimeter. There was considered and compared different models of mutual sensor reflection in the multiprobe microwave multimeter. There was shown and proved that the model in the form of signal flow graph for gain determination does not necessarily use the rule of non touching loop (the Maison rule), and it can be successfully replaced by the matrix and topological reduction.
