Mixed-mode impedance and reflection coefficient of two-port devices [PDF]

, 2012
From the point of view of mixed-mode scattering parameters, Smm, a two-port device can be excited using different driving conditions. Each condition leads to a particular set of input reflection and input impedance coefficient definitions that should be ...

Conservation laws and open systems on higher-dimensional networks [PDF]

, 2008
We discuss a framework for defining physical open systems on higher-dimensional complexes. We start with the formalization of the dynamics of open electrical circuits and the Kirchhoff behavior of the underlying open graph or 1-complex.

Backscattering in silicon microring resonators: a quantitative analysis [PDF]

, 2016
Silicon microring resonators very often exhibit resonance splitting due to backscattering. This effect is hard to quantitatively and predicatively model.
