Mixed_Mode_Sparam2Exploration of the Properties of the Mixed-Mode S-ParametersYonggang Zhou* and Yinchao Chen*,***Department of Electronic Science and Technology Nanjing University of Aeronautics and Astronautics, Nanjing, China **Department of Electrical Engineering University of South Carolina, Columbia, SC, USAAbstract- The paper targets to explore the properties of the mixed-mode S-parameters, which are widely used in the computer PCB and wireless RF industries and have not received serious discussion in the currently published literature. In this paper, in order to compare these properties with the corresponding ones defined in the conventional single-ended S-parameters, we have first developed the symmetric and unitary properties in terms of the mixed-mode S-parameter matrix. Next, we have develope……
