The article presents the analysis and calculation of a two-layer coaxial waveguide with ohmic losses and functional nodes based on it. Coaxial waveguides are widely used in various fields of radio electronics, telecommunications and microwave technology due to their broadband and simple design. However, when designing such systems, it is necessary to take into account various factors that may affect the operation of waveguides. The most significant of these are ohmic losses. The article provides a theoretical analysis and formulation of the diffraction problem for a two-layer coaxial waveguide. Maxwell's equations, boundary conditions have been considered and dependences for complex wavenumbers on the magnitude of losses have been obtained, which makes it possible to determine the attenuation and propagation velocity of the signal in the waveguide. The solution of the diffraction problem of calculating the coaxial terminal load by cross-section and reduction methods has been presented and the dependence of the VSWR of the device on the imaginary part of the dielectric constant of the ceramic sleeve has been determined.
