What is Nonreciprocity? Part II
Abstract
This paper is the second part of a two-part paper on Electromagnetic (EM) Nonreciprocity (NR). Part~I has defined NR, pointed out that linear NR is a stronger form of NR than nonlinear (NL) NR, explained EM Time-Reversal (TR) Symmetry (TRS) Breaking (TRS-B), described linear Time-Invariant (TI) NR media, generalized the Lorentz reciprocity theorem for NR, and provided a physical interpretation of the resulting Onsager-Casimir relations~CalozAWPLNRI2018. This part first explains the TR specificity of lossy and open systems. Next, it proposes an extended version of the S-parameters for all NR systems. Then, it presents the fundamentals of linear-TI (LTI) NR, linear Time-Variant (LTV) Space-Time (ST) modulated NR and NL NR systems. Finally, it addresses confusions between with systems.
