, shown by arrows. These frequencies are in the vicinity of the
hybrid eigenfrequency [8].
We notice that in the vicinity of the Fano resonance, there
appears a
π
-jump in the phase of the second oscillator (see
Fig. 9.3). Below that resonant frequency, both oscillators are in
phase, whereas above the resonant frequency, they oscillate out of
phase.
