Modeling of Microwave Waveguide Systems of Complex Structure

This chapter is devoted to the modeling of microwave systems with complex structural mixed combinations. Here, a mathematical model of the surface impedance of an irregular and complex-walled rectangular waveguide was developed, and the problem of connecting them to each other by opening cracks of different sizes in the complex waveguide microwave paths was solved. At the same time, the problem of modeling the electromagnetic field in a switching device from a rectangular waveguide to a circular waveguide has been solved theoretically and experimentally. Thus, a circular waveguide was placed inside the rectangular waveguide, and in this complex waveguide system, the propagation of the electromagnetic wave and the coefficient of interaction were determined.
