Most techniques for power system analysis model the grid by exact electrical circuits. For instance, in power flow study, state estimation, and voltage stability assessment, the use of admittance parameters (i.e., the nodal admittance matrix) and hybrid parameters is common. Moreover, network reduction techniques (e.g., Kron reduction) are often applied to decrease the size of large grid models...

This paper focuses on the S-parameter method that is a basic method for measuring the input impedance of balanced-fed antennas. The basic concept of the method is summarized using the two-port network, and it is shown that the method can be enhanced to the unbalanced antennas using a formulation based on incident and reflected waves. The compensation method that eliminates the influence of a me...

The measurement of the polarization and phase distributions of a wave field is an often posed problem [1,2]. Usually, the polarization is determined by measuring the Stokes parameters, but without access to the phase. Phase shifting interferometry (PSI) may be used to determine the phase, but without considering the polarization as a measurand. In this work, we will propose an interferometric a...
