<p>The results of the experimental study are compared with the calculated ones obtained using an approximate method for determining the effective permittivity and propagation constant of a partially filled waveguide (PWF) presented in [1]. The approximate method differs from the existing ones in that it is not necessary to solve transcendental dispersion equations to determine the propagation constant in a rectangular waveguide with a PDF. In particular, the results of a theoretical calculation of the dependences of the size of the wide wall of the PWF with cross-sectional dimensions of 23 × 10 mm on the change in the fill factor along the wide wall of the waveguide at a frequency of 10 GHz, the wavelength, the wave impedance of the PWF, and the propagation constant on the change in the fill factor along the wide wall, waveguide in the frequency band 6–14 GHz for modification 2–1–2 (thin dielectric plates near the side walls) and 1–2 (thin dielectric plate near one side wall) for the H<sub>10</sub> type wave are presented.</p>
<p>Experimental studies were carried out using a laboratory setup consisting of a signal generator, a voltage ratio meter, a measuring line based on a rectangular waveguide, to the output of which a short circuit was connected. Dielectric plates (PTFE Ф4) 10 mm wide, 2 mm and 4 mm thick, and 253 mm long were installed inside the rectangular waveguide of the measuring line. The maximum relative error of the results of experimental studies for modifications 2-1-2, 1-2 does not exceed 15%, in particular, for modification 2-1-2 it is less than for 1-2.</p>
<p>The presented results confirm the feasibility and high accuracy of calculating the electrodynamic characteristics of the PWF by the approximate method [1].</p>
<p>The reliability and validity of the results obtained is ensured by a sufficiently high convergence of the calculation results with the experimental ones, under boundary conditions with known results, the convergence of the obtained formulas in units of measurement.</p>}, number={88}, journal={Visnyk NTUU KPI Seriia - Radiotekhnika Radioaparatobuduvannia}, author={Каращук , Н.
