摘要：
The role of the local absorber in suppressing self-excitation of a relativistic plasma surface-wave microwave amplifier is investigated. The thus obtained amplifier self-excitation conditions are analyzed for a wide range of parameters employed in plasma microwave electronics experiments. Requirements on an absorber for suppression of amplifier self-excitation are given.
