Root-locus analysis of exceptional points in coupled-resonator networks


Recently, the engineering of exceptional points (EP) in optical and electrical systems becomes a multi-disciplinary field in physical sciences, because phase transitions often occur near such points. In this paper, we indicate that the engineering of EPs can be treated as a root-locus problem that is well-know in control theory. We formulate two root-locus… (More)
