WebAlso, the transformation matrix elements do not always behave smoothly due to eigenvector switchovers. In this paper: a) shunt conductances are included in eigenvalue/eigenvector calculations; b) transformation matrices are considered to be complex and frequency-dependent and; c) a procedure to avoid eigenvector switchovers is used.
In electrical engineering, admittance is a measure of how easily a circuit or device will allow a current to flow. It is defined as the reciprocal of impedance, analogous to how conductance & resistance are defined.
