Various regimes of hybrid, bulk-surface, modes being excited in the clinotron oscillator with a sheet electron beam and nonuniform grating have been studied theoretically. It is shown that higher output power of the hybrid mode in comparison with pur

The interaction of the modes with different variations along grating lamella occurring in a clinotron with periodically modified grating due to the profile of the clinotron circuit cross-section, has been studied. The simulation results demonstrate t

Peculiarities of a THz non-resonant clinotron in a regime of surface-radiating backward wave arising due to periodically modified grating have been presented. The simulation results demonstrate that the feedback and efficiency of the radiation output

Recently proposed methods for generation of entangled (quantum correlated) signals directly in microwave frequency range give more chances for design of QR for long-range applications. In such applications, the range resolution capability is of a gre

Ground Noise SAR exploits either special antenna with pattern synthesis or Tx/Rx antenna motion along a rail path. In both cases, the azimuth resolution is limited by the available/achievable length of Tx/Rx physical antenna motion. However, in many
