Modeling the Distribution of the Electromagnetic Field in the Device for Adding the Power of Microwave Magnetrons

Abstract

Substantiation of the physical nature of adding the power of magnetron generators in the device’s waveguide, assessment of the electromagnetic properties of objects without experimental verification, testing of scientific and technical hypotheses for adequacy without creating prototypes are possible by modeling the distribution of the electromagnetic field in the CST Studio program. (Research purpose) The research purpose is to simulate the distribution of the electromagnetic field in the device for adding the power of microwave magnetrons. (Materials and methods) CST Studio software was used to design models of the distribution of the electromagnetic field in the device for adding the power of microwave magnetrons. (Results and discussion) Models of the distribution of the electromagnetic field in the device for adding the power of microwave magnetrons was designed using the CST Studio program. It was found that at operating frequencies of 1, 3, 4 and 5 GHz, the distribution of the electromagnetic field of different densities is dispersed throughout the volume of the waveguide, which does not allow the use of a waveguide of the appropriate size to perform the basic functions of transmission and distribution of microwave energy, while at the operating frequency of 2 GHz the basic operating conditions of the waveguide are observed. It was found that, within the boundaries of the waveguide of the developed device, the force lines of the electromagnetic field propagate from the surface of the emitters into the space of the waveguide, are reflected from the walls, distributed over the volume of the waveguide, and rush to the output open end. (Conclusions) It was found that the generated pulses of the power flow of electromagnetic energy of an ultrahigh frequency of the flux of two magnetrons, corresponding to a value of 116 Volts·Amperes at square meter, propagating throughout the volume of the waveguide at different time intervals according to the operating frequency, take a one-way travel of their electromagnetic field lines from short-circuited end in the direction of the open part of the waveguide, are localized with the highest concentration in the output horn end of the waveguide, which is explained by the phenomena of power addition after providing traveling wave due to the coordination of the metric dimensions of the waveguide and the working wavelength.
