In other words, the things become much more complicated, and the circuit components are no more simple - for example, you may find a capacitor is actually a weird combination of number of capacitances, inductances and resistors.. all that can be sometimes modelled by equivalent schematic, or, what is more practical, we just take s-parameters of the component, valid for certain frequency range, and we are not bothered with actual physical component (black box approach). |
And what you're saying is that the 'equivalent circuit' required to achieve stability at the ~1ms pulse frequency is far more complicated than the one Alex has forwarded us.
Let's not go further on this .. this is Alex's model, and be both know we could design it all for him. But as Steven (& Carl) have pointed out, there is no astronomical behavioural evidence to support the concept of active behaviour of 'electrical analogous components' (plasma double layer capacitors, etc) in the first place … I have pointed out that it cannot even be modelled in the lab, using the plasma scaling transformations developed by Alven etc .. you have pointed out that the stability of ROs is inadequate.
That should suffice.
