“…The Relativistic Klystron Amplifier of the Naval Research Laboratory has generated a power of 15 GW at a frequency of 1.3 GHz in a single-shot, ∼ 50 ns pulse [2]. The maximum power obtained with a single-mode relativistic BWO in the X band was 3 GW with ∼ 100 J energy in a single pulse [3]. The efficient radiation of the intense electromagnetic wave generated by HPM source is an indispensable premise of such a HPM application as the directed energy weapon (DEW), radar system [4,5].…”

Abstract-Design aspects of high efficiency profiled circular horn feeds with smooth wall for the high-power microwave (HPM) system are presented in this paper. The modal content at the circular aperture of horn necessary to closely approximate a linear polarized Gaussian distribution is established. Slope discontinuities along the axis of the horn are then used to generate the necessary waveguide modes with the appropriate amplitudes and phases at the aperture. The performance of the horn is calculated using the mode matching technique. Significant improvement in the performance of radiation over a straight conical horn can be achieved on the premise of high power capacity. The excellent correspondence between the simulations by MMT codes and CSTMWS (CST microwave studio) supports this conclusion.

“…For practical devices, operation at reduced voltages, possibly no more than 500 kV, is preferable. So far, the maximum power achieved in slightly oversized backward wave oscillator (BWO) with operating at 550 kV is about 0.8 GW at 10-GHz frequency [7].…”

Abstract-Results of theoretical and experimental studies of a GW-class, large diameter microwave oscillator are presented. The device consists of a large cross-section (overmoded), slow-wave structure with a unique profile of wall radius specifically designed to support surface waves and to provide a strong beam-wave coupling at moderate voltage (500 kV), an internal adjustable microwave reflector, a coaxial microwave extraction section, and a coaxial magnetically insulated field emission electron gun. In preliminary experiments carried out at 8.3 GHz, the power level exceeding 0.5 GW and efficiency of 15% have been measured calorimetrically.Index Terms-High-power microwave (HPM), overmoded, surface-wave oscillator.

“…1,2 In order to make it more applicable in scientific research and to some practical applications, much effort has been directed in increasing the radiation power and pulse length in the past years. For a narrow band high power microwave (HPM) device, most of the researches are trying to control the beam-wave interaction occurred at a single frequency under certain microwave modes.…”

An idea of azimuthally dividing the slow wave structure (SWS) of a relativistic backward wave oscillator (RBWO) into two parts is introduced to realize a bifrequency oscillation. To enhance the stability of this device, two sectorial waveguides are inserted into the SWS specially. The synchronization condition that is necessary to get a sustainable microwave output is derived. In Particle in cell simulation, bifrequency microwave at frequencies of 9.7 GHz and 9.87 GHz is generated with average power of 0.66 GW, conversion efficiency is 15.8% when beam voltage is 520 kV and current 8 kA
