Abstract :

Submillimeter waves become even more widely used in satellite technologies. The evolution of the circuit technology of send/receive devices is largely determined by the quality of transmission lines. The advanced circuit technologies are used not only in power transmission but also as a basis for construction of filters, antennae, mixers, splitters, polarizers, etc. We provide an overview of new types of transmission lines based on planar cut-off waveguides with or without dielectric filling. The idea for the new class of transmission lines was inspired be a discovery made in Microwave Devices Laboratory, Karazin State University, Kharkiv, Ukraine. The laboratory found that cut-off waveguides are able to maintain Eigen-oscillation mode in their branching areas acting as semi-open resonators. Using an original method of partial areas, we obtained and calculated dispersion relations that describe the spectrum dynamics of normal modes. The characteristic feature of the method used consists in term by term satisfaction of the boundary conditions for the electric component of a mode; that technique ensures a high convergence rate of the calculations. We provide calculated losses for the most promising transmission lines. The calculation results demonstrate the advantages of these lines over the known line types.
