“…The simulator FEKO, as we think, automatically takes into account the electrical field singularity on the mathematically sharp slot edge. Unlike the papers in [28][29][30], we did not supply the basic functions in Equation (2) with the factor accounting the E field singularity at the edges of the slot. Using 11 basic functions in Equation (1), we obtained a good converged value for f res .…”

A scattering problem for two semi-infinite rectangular waveguides coupling through a narrow slot cut in the common end wall of the two waveguides is solved. The slot is partially filled with a dissipative or perfect dielectric insert. A mathematical model based on continuity of tangential components of magnetic field vectors on both surfaces of the diaphragm in the coupling waveguides is proposed. The magnetic field in the slot is represented by a set of slot eigenwaves. The electrical field distribution function is used as a basis function in the Galerkin's procedure allowing to find unknown amplitude coefficients. Simulation and experimental measurement have been carried out. Dependences of scattering parameters upon the wavelength were studied for various geometric parameters, insert position in the slot, and insert material permittivity and losses. A good agreement between simulation results and experimental data is obtained. It was shown that an estimate of the insert permittivity and losses can be done for unknown materials using experimental and simulated data.

“…We consider a transverse metal diaphragm with complex aperture placed in regular waveguide with air filling excited by the dominant mode . The total electric fields in the waveguide from the side of the excitation (I) and the opposite side (II) of the diaphragm are the fields superposition of excited propagating and nonpropagating TE‐ and TM‐modes, respectively.…”

“…It was shown in Zemlyakov et al that a waveguide resonant diaphragm with an aperture in the form of the rectangular window with two L‐shaped metal ridges has both a pole and zero in its amplitude‐frequency characteristic. The results indicate that this waveguide resonant diaphragm is described by more complex equivalent circuit, and it can potentially be used as parallel and series LC circuit.…”

A novel approach to the synthesis of waveguide band-pass elliptic filters on the transverse metal resonant diaphragms with the complex aperture is proposed.The aperture of the diaphragm is considered to be a rectangular window with two L-shaped metal ridges. For the complex conductivity of the diaphragm, we solve the corresponding electrodynamic problem. We also construct and investigate an equivalent circuit of the resonant diaphragm containing a series-parallel LC circuit. The geometry of the diaphragm aperture is found to be corresponding to the parameters of the equivalent circuit. We construct a third-order elliptic filter and provide a computer simulation of the diaphragms satisfying the amplitude-frequency characteristics of its resonators. We show that some resonators can be located on one complex resonant diaphragm, which then reduces the length of the filter. The band-pass filter for a rectangular waveguide WR137 is developed and manufactured. The central frequency of the filter is 6.6 GHz, the passband width 7.5 % with return loss of −20 dB, and the total length is 34 mm.
