Item Comparative analysis of novel compact and usual smooth 90-degree twists(Видавництво Національного університету "Львівська політехніка", 2009) Kirilenko, A. A.; Kulik, D. Yu.; Rud, L. A.; Sverdlenko, A. E.Two types of compact 90-degree twists whose transformer sections are square waveguides with two square or stepped ridges are considered. Twist electromagnetic models are based on the mode matching and generalized scattering matrix techniques. Good agreements between calculated and experimentally measured characteristics of manufactured prototypes of the both type twists in the 23×10 mm waveguide are demonstrated. On the base of specially studies carried out, it is shown that, at close or even better performance, the lengths of proposed twists are ten and more times less than the ones of conventional smooth twists.
