Abstract: We present a modification of the method for synthesizing the surface of waveguide transducers, which are developed at the Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS), in combination with solving of a system of scalar integral equations for the surface electric current. Since the synthesis procedure operates on the components of the electromagnetic field on the surface, which are unambiguously related to the current, the specified equations are integrated into it seamlessly. The equations are derived from the original vector integral equation of iterative physical optics, which is a method for analysis of electromagnetic fields in oversized systems, for a waveguide with a smooth wall deformation. The method is used in the calculation of high-power microwave devices (gyrotrons) and for the synthesis of waveguide emitters that convert the high-frequency operating mode into a quasi-Gaussian field distribution at the output by using a smooth shallow deformation of the waveguide. The possibility of significantly accelerating the synthesis while maintaining the high efficiency of the obtained profile is shown using the example of an emitter operated at a frequency of 184 GHz with the TE28.13 mode.
