Hello,When we look at a single port resonator device in a frequency domain we have deep at S11 plot which means that all energy went from port 1 and doesnt come back and the energy is traped inside the cavity .

In here we have another situation where a phase delay of a reflected signal cancels the original signal.
Why its called a resonance?
Thanks.
