Abstract
Spurious oscillations near edges of pass-bands due to periodicity (π and 2π) as well as edges due to manufacturing tolerance (3π/2) might develop in coupled cavity TWTs (CC-TWTs) and limit their performance. Modeling of spurious oscillations is challenging computational task since the beam-wave interaction occurs at several frequencies simultaneously. In general, stability analysis is a non-linear problem since starting conditions for spurious oscillations might depend on input power at operating frequency.
