description |
The study of peculiarity of influence of the impedance insertions on the electrodynamic characteristics of the rectangular waveguide junctions, which are widely used in the antenna-waveguide devices, is important for practical applications. A mathe-matical model for E-plane T-junction of rectangular waveguides with a three-element vibrator-slot coupling structure was built using approximate analytical solutions of equations for induced currents by a generalized method of electro-magneto-motive forces. The distinctive feature of the model is the usage of variable surface impedance along the monopole axes and constant impedance, distributed over the end wall of the lateral semi-infinite waveguide. Multiparameter energy characteristics of the junction in the single-mode waveguides are presented including the case of meta-material coating the end wall of the lateral waveguide. The possibility of efficient use of impedance coatings as control element for power division between the output waveguide junction arms is shown. |
