A Magnetron with Two Energy Outputs: Simulation and Experiment | Chapter 3 | Current Perspective to Physical Science Research Vol. 2

 This affiliate presents the theoretical and exploratory results of creating the new magnetron design with two strength outputs (or dual-production magnetron) to solve the questions for frequency tuning, develop its establishment, and extend use possibilities. Due to their extensive use in miscellaneous human endeavors, including military electronics, industry, farming, research, and medicine, magnetrons have become ultimate well-known and direct microwave alternator. The modified magnetron's primary utility has been recognized both tentatively and theoretically. The availability of a second strength output in the anode block is the basic differentiating characteristic concerning this magnetron (for instance, in contrast to the standard magnetron accompanying a single productivity). The mathematical models for the energized matter-wave interaction and the resonant anode block are depicted. The anode block's dispersion features for cavities with various shapes are provided. According to hypothesis, the interference of RF fields upset several times in the profound anode block made up of microscopic and large craters (resonators) leads to the formation of the total RF field in the interaction room. For the PIC simulation of power-wave interaction in the two-fold-output magnetron, the non-linear whole of equations is established as a self-consistent scheme containing the equation of motion (for energized matter stream), the equation of excitement (for RF field), and Poisson's equation for manipulative the space-charge field. The fundamental feature of the self-consistent whole of equations is a new treasure for determining the Coulomb interplay forces. Implementing the mathematical model made it attainable to gain new knowledge about the magnetron's material processes and determine allure output characteristics.  On the operating repetitiveness of ~ 13.34 GHz, at an anode voltage of 495 V, a magnetic field of currents of ~ 0.25 T, and with chill of the magnetron, there were obtained the following confining values: the RF production power of ~ 14.6 W and the capacity conversion efficiency of ~ 40.8%. Applying the second strength output lengthened the magnetron's functionality and executed the modes of frequency bringing into harmony (adjustment) and counterweight. The simulation results are in good contract with the experiment. As a result, these studies have demonstrated the animation of computational experiments for modeling the tangible phenomena in a magnetron's interplay space and the resonant wholes' electrodynamic features. The electrodynamic characteristics of rising-sunlight systems with miscellaneous cavity designs are fake, and the findings are likely. It is demonstrated that a rising-star system accompanying a "hole-and-slot" construction has more options when selecting an swinging's operational fad's resonant frequency.
