Effects of synchronization in a system of two coupled oscillators with time-delayed feedback are investigated. Phase space of a system with time delay is infinite-dimensional. Thus, the picture of synchronization in such systems acquires many new features not inherent to finite-dimensional ones. A picture of oscillation modes in cases of identical and non-identical coupled oscillators is studied in detail. Periodical structure of amplitude death and "broadband synchronization" zones is investigated. Such a behavior occurs due to the resonances between different modes of the infinite-dimensional system with time delay.

“…At higher values of current, non-stationary selfmodulation regimes are observed (c.f. [4,5]). Thus, the three-cavity two-stage oscillator can provide over 100 W output power in W band at substantially reduced level of the beam current (0.2-0.3 A).…”

We present the results of theoretical analysis and numerical simulation of a two-stage multiple cavity klystron oscillator in W band. Small-signal theory of the oscillator is developed and start-oscillation current and oscillation frequency are calculated. Output power and efficiency is determined from large-signal time-domain particle-in-cell simulation. Oscillators with different number of cavities are compared.
