“…The analysis carried out for different types of joints showed that an agreement acceptable for practice can be achieved only in a narrow band of frequencies and at a fixed ratio between the shoulder dimensions. Therefore, the task of ensuring a high-quality agreement is impossible to solve without constructive or other types of changes in the structure [4][5][6][7]. High-frequency devices lack the necessary elements for their operation, so their production must be preceded by computer design of the relevant electrodynamic structure, which includes three stages: 1.…”

At present, the requirements for flying machines, in terms of increasing flight speeds, maneuverability, and flight intensity, significantly expand the range of tasks to be solved by the radio-electric equipment of these machines. Therefore, during their design and construction, problems arise with the placement of a large number of antennas and radio-electronic devices. In addition, for maneuvering and flight dynamics, it is not allowed to place additional protrusions on the devices. From the obtained results, we can assume that the electrodynamic properties of the considered system can be changed by the variation of the system's feeding mode.

“…Recently, a lot of work has been published to analyse and design the three-and higher order multiport port waveguide junctions with different types of artificial inclusions [9][10][11][12][13][14][15][16][17][18]. Besides, various optimization techniques have been proposed to optimize the geometric and material parameters of these junctions [19][20][21][22][23].…”

Abstract-This paper proposes a rigorous theory of the H-plane fourport (cruciform) waveguide junction with a conducting diaphragm and a dielectric layer in the main (input) waveguide arm. This theory is based on the mode matching method in conjunction with Fourier transform technique and including the edge conditions in vicinity of the diaphragm edges. The numerical analysis of the cruciform waveguide junction is done, and optimal parameters of inclusions are predicted based on the minima of voltage standing wave ratio (VSWR) in the main arm.
