Effect of the External Coupling of Cavities on the Stability and Output Power of a Relativistic Magnetron

Thus, the results of our investigations show that the external coupling of cavities in a relativistic magnetron significantly influences on the spectral and energetic characteristics of the oscillations. The original configuration of the coupling circuit is proposed, based on the scheme with common dissipative elements. This significantly improves the output microwave radiation signal parameters. One can expect that using a coupling channel with many radiators will make possible to create stable, ultrahigh-power, high-directivity radiation sources
