Reflectors Effect on Increasing the Output Power of Reflex Triode

The reflex triode is one of the varieties of vircators that areamong several types of high power microwave sources. The Main application of these tubes is the disruption of enemy systems by creating a strong electromagnetic field on the target. This paper presents a comparison of experimental and simulation results of a reflex triode.Experimental and simulation results are in good agreement. The software used for simulationis the CST STUDIO SUITE. It is based on the Finite Integration Technique (FIT) and includes a particle in cell code. In previous studies, with the use of two disk-shaped and strip reflectors in this tube, the electric field output was increased by a maximum of 126%. In this research for the first time with the introduction and use of wall reflector, the electric field output was increased by 193%. It was shown that each of the disk-shaped, strip, and wall reflectors increased 37% and 29% of the output electric field, respectively.A variation in the position of the reflector causes a variation in the radiation power. This variation is periodic.
