MAGNETIC INSULATED VIBRATOR DEVICE Russian patent published in 2000 - IPC

FIELD: electrical engineering. SUBSTANCE: device has pulsating voltage oscillator, cathode electrode and anode electrode insulated from the cathode one. The electrodes are placed into magnetic field. The anode electrode has modulating section designed as wave guide enveloping the cathode electrode and a section for forming virtual cathode as wave guide having cross-section area greater than that of modulating section wave guide. It ends with horn having window for making radiation output. The modulating section is designed to be completely or partially corrugated. EFFECT: higher radiation efficiency. 2 cl, 1 dwg
