Jan 5 at 14:47 comment added Josh23 Hello Andy ,yes i did, i just want a simple example of a two port system where i could calculate the reflection coefficients and see on the mathematical level why the energy is locked in the middle during resonance.Thanks.
Jan 4 at 12:47 comment added Andy aka @Josh23 what are your knowledge levels on transmission lines? Do you understand reflection coefficient and how reflections can appear to change input impedances? Have you studied the quarter wave impedance transformer?
Jan 4 at 12:29 comment added Josh23 Hello Andy ,i'll be glad if there is some transmission line example i would see your good explanantion.
Jan 4 at 9:17 comment added Andy aka It isn't sufficient to regard it this way as I have pointed out in my previous comment and my answer.
Jan 4 at 4:27 comment added Josh23 Hello Andy, Yes I understand the VIA is a discontinuity, but in resonance the energy is stuck in the middle so its not absorbed in none of the ports straight away.so with using the discontinuity point could you please explain how that the energy is stuck in the middle with an example so i could simulate? Thanks.
Jan 3 at 22:22 comment added Andy aka You can but it's more standard to think of it as a blocking impedance. But, a blocking impedance isn't sufficient to explain a plunging S21 hence, we need to think of the via as creating a transmission line discontinuity also.
Jan 3 at 21:46 comment added Josh23 Hello Andy, can i think that the resonator causes the signal to be trapped in the medium going back and forth and not reaching the destination? thanks.
